Check Digit Verification of cas no

The CAS Registry Mumber 100330-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100330-20:
(8*1)+(7*0)+(6*0)+(5*3)+(4*3)+(3*0)+(2*2)+(1*0)=39
39 % 10 = 9
So 100330-20-9 is a valid CAS Registry Number.

Chemoselective alkylation of thiols: A detailed investigation of reactions of thiols with halides

Khurana,Sahoo

, p. 1691 - 1702 (2007/10/02)

Arylthiols, aralkylthiols and alkane thiols can be readily alkylated by alkyl/aralkyl halides in presence of K2CO3/DMF to yield unsymmetrical sulphides in nearly quantitative yields. 2-Mercaptoethanol gave the thioether chemoselectively.
