4669-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4669-54-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4669-54:
(6*4)+(5*6)+(4*6)+(3*9)+(2*5)+(1*4)=119
119 % 10 = 9
So 4669-54-9 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
