Check Digit Verification of cas no

The CAS Registry Mumber 21172-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,7 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21172-92:
(7*2)+(6*1)+(5*1)+(4*7)+(3*2)+(2*9)+(1*2)=79
79 % 10 = 9
So 21172-92-9 is a valid CAS Registry Number.

A one-pot three-component synthesis of dithiocarbamates starting from vinyl pyridines and vinyl pyrazine under solvent- and catalyst-free conditions

Halimehjani, Azim Ziyaei,Martens, Jürgen,Schlüter, Torben

, p. 3958 - 3965 (2016)

A novel and efficient one-pot three-component reaction for the synthesis of dithiocarbamates at room temperature under solvent- and catalyst-free conditions, starting from readily available amines, CS2and vinyl pyridines and vinyl pyrazine is reported. Excellent yield, green reaction conditions, and complete regioselectivity toward anti-Markovnikov adducts are particular advantages of this work.
