Check Digit Verification of cas no

The CAS Registry Mumber 142196-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,9 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142196-39:
(8*1)+(7*4)+(6*2)+(5*1)+(4*9)+(3*6)+(2*3)+(1*9)=122
122 % 10 = 2
So 142196-39-2 is a valid CAS Registry Number.

Kilitoglu, Bahar,Arndt, Hans-Dieter

scheme or table, p. 720 - 723 (2009/08/07)

The Evans-Chan-Lam variant of the Ullman condensation has been explored to deliver O-arylated tyrosines and tyrosinyl peptides. Key modifications for success were the slow addition of boronic acids to the phenol-catalyst mixture. Selectivity and scope are investigated. Georg Thieme Verlag Stuttgart.
