Check Digit Verification of cas no

The CAS Registry Mumber 233610-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,3,6,1 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 233610-77:
(8*2)+(7*3)+(6*3)+(5*6)+(4*1)+(3*0)+(2*7)+(1*7)=110
110 % 10 = 0
So 233610-77-0 is a valid CAS Registry Number.

Referential example 3, (2010/11/29)

2-Sulfonylpyridine derivatives can be industrially produced efficiently by reacting a sulfonyl cyanide derivative with an α,β-unsaturated carbonyl compound and a 2-{[(2-pyridyl)methyl]thio}-1H-benzimidazole skeleton can be formed in one step in a good yield by reacting this type of the 2-sulfonylpyridine derivative with a 2-methylthio-1H-benzimidazole derivative in the presence of an organolithium compound.
