Check Digit Verification of cas no

The CAS Registry Mumber 51861-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,6 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51861-57:
(7*5)+(6*1)+(5*8)+(4*6)+(3*1)+(2*5)+(1*7)=125
125 % 10 = 5
So 51861-57-5 is a valid CAS Registry Number.

A facile method for the synthesis of thiocarbamates: Palladium-catalyzed reaction of disulfide, amine, and carbon monoxide

Nishiyama, Yutaka,Kawamatsu, Hiroaki,Sonoda, Noboru

, p. 2551 - 2554 (2005)

(Equation Presented) A new method for the synthesis of thiocarbamates has been developed. When dialkyl or diaryl disulfides were allowed to react with secondary amines and carbon monoxide in the presence of a catalytic amount of a palladium complex, the thiocarbamates were obtained in moderate to good yields. In contrast to that of secondary amines, in the reaction of a primary amine, no formation of thiocarbamate was confirmed, but urea was formed in good yield.

The insertion reaction of isocyanides with thiocarbamates and selenocarbamates in the presence of a Pd(0) catalyst to selectively give 2-oxoethanimidothioates and -selenoates is reported. This is the first example of the insertion of an isocyanide into a
