Check Digit Verification of cas no

The CAS Registry Mumber 84960-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,6 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84960-32:
(7*8)+(6*4)+(5*9)+(4*6)+(3*0)+(2*3)+(1*2)=157
157 % 10 = 7
So 84960-32-7 is a valid CAS Registry Number.

SRN1 Mechanism in Heteroaromatic Nucleophilic Substitution. Reactions Involving Certain Dihalogenated ?-Deficient Nitrogen Heterocycles

Carver, David R.,Greenwood, Thomas D.,Hubbard, James S.,Komin, Andrew P.,Sachdeva, Yesh P.,Wolfe, James F.

, p. 1180 - 1185 (2007/10/02)

Photostimulated reactions of 2,6-,2,3-, 3,5-, and 2,5-dihalopyridines (1a-e) with pinacolone potassium enolate (2) in liquid NH3 lead to facile replacement of both halogens via a modified SRN1 mechanism, which does not involve intermediate formation of monosubstitution products.The potassium salts of phenylacetonitrile (12a) and α-ethylphenylacetonitrile (12b) react with 2,6-dibromopyridine (1a) under similar conditions to afford a mixture of mono- and disubstituted products via a related SRN1 process. 4,7-Dichloroquinoline (16) undergoes radical-chain displacement of chloride from C4 with enolate 2. 2,6-Dichloropyrazine (18) and 2,3-dichloropyrazine (20) also undergo monosubstitution with 2 and diisopropyl ketone potassium enolate (22), but these reactions appear to be mainly addition-elimination (SNAr) processes.Treatment of 3,6-dichloropyridazine (27) with 22 results in addition of 22 to C4 of the substrate.Photoassisted reaction of 2,4-dichloropyrimidine (31) with 12a leads to exclusive chloride displacement from C4 via the SRN1 mechanism.
