Check Digit Verification of cas no

The CAS Registry Mumber 96872-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,8,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 96872-40:
(7*9)+(6*6)+(5*8)+(4*7)+(3*2)+(2*4)+(1*0)=181
181 % 10 = 1
So 96872-40-1 is a valid CAS Registry Number.

Phenols as starting materials for the synthesis of arylstannanes via SRN11

Chopa, Alicia B.,Lockhart, María T.,Dorn, Viviana B.

, p. 1425 - 1429 (2008/10/08)

Phenols are converted into aryl diethyl phosphate esters (ArDEP), which on reaction with sodium trimethylstannide (1) or sodium triphenylstannide (2) in liquid ammonia afford arylstannanes by the SRN1 mechanism. Thus, the photostimulated reaction of phenylDEP (3), (4-methoxyphenyl)DEP (4), (4-biphenyl)DEP (5), (1-naphthyl)DEP (6), (2-naphthyl)DEP (7), and 2- (34), 3- (32), and (4-pyridyl)DEP (35) with 1 leads to monostannylated product in fair to excellent yields (20-98%). Also, substrates containing two or three leaving groups react with 1 under irradiation, affording the corresponding di- or tristannylated aryl compounds. With tetraethyl m-phenylene bisphosphate (15), tetraethyl p-phenylene bisphosphate (21), (4-chlorophenyl)DEP (22), and 1,3,5-tris(diethylphospho)benzene (30), the di- or trisubstitution products 1,3-bis(trimethylstannyl)benzene (19) (79%), 1,4-bis(trimethylstannyl)benzene (23) (95 and 97%), and 1,3,5-tris(trimethylstannyl)benzene (31) (57%) are obtained, respectively. Also, the reaction of 6 and 7 with 2 leads to substitution products in quantitative yields, and the reaction of 21, 22, and (4-bromophenyl)DEP (24) with 2 affords 1,4-bis(triphenylstannyl)benzene (38) in high yields (70-100%). On the other hand, the results obtained in the photostimulated reaction of 24 and (4-iodophenyl)DEP (25) with 1, as well as in the reaction of 25 with 2, clearly indicate a fast HME reaction.

Reactions of haloarenes, haloheteroarenes and dihalobenzenes with triphenylstannyl anions in DMSO and acetonitrile

Lockhart, Maria T.,Chopa, Alicia B.,Rossi, Roberto A.

, p. 229 - 234 (2007/10/03)

We studied different haloarenes, haloheteroarenes and dihalobenzenes with Ph3Sn- ions in DMSO or acetonitrile (CH3CN) as solvents, in the dark or under irradiation to determine whether the halogen metal exchange (HME) reaction or the SRN1 process prevails. With p-chloroanisole the photostimulated reaction is sluggish in DMSO. There is an HME reaction with 2- and 3-chlorothiophene. Bromoarenes (p-bromoanisole, p-dibromobenzene and 1-bromonaphthalene) and p-iodoanisole react with Ph3Sn- ions faster by an HME mechanism than by the SRN1 process. In the photostimulated reaction of 1-chloronaphthalene, 2-chloro and 3-chloropyridines with Ph3Sn- ions in DMSO, the substitution products are obtained in 72, 82 and 93% yields, respectively. With p-dichlorobenzene the di-substitution product is obtained in 90% yield. All these reactions occur by the SRN1 mechanism. Yields improve when the reactions are carried out in DMSO rather than in CH3CN.
