Check Digit Verification of cas no

The CAS Registry Mumber 129841-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,4 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129841-41:
(8*1)+(7*2)+(6*9)+(5*8)+(4*4)+(3*1)+(2*4)+(1*1)=144
144 % 10 = 4
So 129841-41-4 is a valid CAS Registry Number.

Reactions of α-Thio Carbanions with Aryl Isothiocyanates

Doelling, Wolfgang,Vogt, Almut,Sperk, Katrin,Augustin, Manfred

, p. 621 - 623 (2007/10/02)

Aryl isothiocyanates react with O-alkyl S-alkoxycarbonylmethyl thiocarbonates 1, S-cyanomethyl dimethyldithiocarbamate 4, and ethyl (thiobenzoylthio)acetates 7 in the presence of strong bases, followed by alkylation with methyl iodide or alkyl bromoacetates, to give substituted 1-cyanovinyl dimethyldithiocarbamates 6, and substituted azetin-2-ones 10, respectively.
