3138-80-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3138-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3138-80:
(6*3)+(5*1)+(4*3)+(3*8)+(2*8)+(1*0)=75
75 % 10 = 5
So 3138-80-5 is a valid CAS Registry Number.

A facile, high-yielding method for the conversion of halides to mercaptans

Bieniarz,Cornwell

, p. 939 - 942 (2007/10/02)

An efficient, high-yield, one-pot preparation of alkyl and activated aryl mercaptans is presented. The method relies on sodium thiophosphate displacement of the halide, followed by mild hydrolysis of the intermediate phosphorothioate.
