Check Digit Verification of cas no
The CAS Registry Mumber 161186-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,8 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 161186-28:
(8*1)+(7*6)+(6*1)+(5*1)+(4*8)+(3*6)+(2*2)+(1*8)=123
123 % 10 = 3
So 161186-28-3 is a valid CAS Registry Number.

General route to phosphonodithioic acid derivatives
Martin,Wagman,Zipp,Gratchev
, p. 7957 - 7958 (2007/10/02)
A general procedure for the synthesis of esters of phosphonodithioic acids has been developed. The method involves the reaction of the Grignard reagents 2a-h with 2-chloro-1,3,2-dithiaphospholane (1) to give 3a-h that were sulfurized using elemental sulfu
