89237-29-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89237-29-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,3 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89237-29:
(7*8)+(6*9)+(5*2)+(4*3)+(3*7)+(2*2)+(1*9)=166
166 % 10 = 6
So 89237-29-6 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS OF SOME CIS 2,3-DISUBSTITUTED CYCLANONES RING SIZE INFLUENCE ON THE STEREOSELECTIVITY OF 2-SUBSTITUTED ENDOCYCLIC ENOLATES PROTONATION

Hatzigrigoriou, E.,Wartski, L.,Seyden-Penne, J.,Toromanoff, E.

, p. 5045 - 5050 (2007/10/02)

Conjugate addition of carbanionic reagents formed from aryl- or phenyl-thioacetonitriles 1a-c and 2 to 2-methyl and 2-phenyl 2-cyclohexenone or 2-methyl 2-cyclopentenone, followed by acidic quench, under kinetic control, leads to different ratios of cis and trans 2,3-disubstituted cyclanones according to ring size.From 2-methyl and 2-phenyl 2-cyclohexenone, the cis isomer is highly predominant (85 to 98percent).From 2-methyl 2-cyclopentanone a cis/trans mixture is obtained: the cis isomer only predominates when a bulky reagent (1c) is used (80percent); in the other cases a mixture of nearly 1:1 is obtained.
