Check Digit Verification of cas no

The CAS Registry Mumber 22181-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22181-31:
(7*2)+(6*2)+(5*1)+(4*8)+(3*1)+(2*3)+(1*1)=73
73 % 10 = 3
So 22181-31-3 is a valid CAS Registry Number.

The α-Effect in Benzyl Transfers from Benzylphenylmethyl Sulfonium Salts to N-Methylbenzohydroxamate Anions

Fountain,Tad-y, Darlene B.,Paul, Timothy W.,Golynskiy, Mikhail V.

, p. 6547 - 6553 (2007/10/03)

The investigation of the occurrence of the α-effect in group transfers from phenyldialkyl sulfonium ions where one alkyl group is benzyl allows an assay of the effect of changing the nature of the C atom being transferred. The size of the α-effect responds to increasing electron demand, as methyl transfers do. Quantitative relationships between the size of the α-effect are established from both the nucleophilic side and the leaving group side of the SN2 transition state.
