21168-04-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21168-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,6 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21168-04:
(7*2)+(6*1)+(5*1)+(4*6)+(3*8)+(2*0)+(1*4)=77
77 % 10 = 7
So 21168-04-7 is a valid CAS Registry Number.

A new method for the synthesis of dithiocarbamates by CuI-catalyzed coupling reaction
Liu, Yunyun,Bao, Weiliang
, p. 4785 - 4788 (2007)
The Ullmann-type coupling reaction of sodium dithiocarbamates with aryl iodides and vinyl bromides catalyzed by CuI/N,N-dimethylglycine proceeds smoothly in DMF at 110 °C to give corresponding dithiocarbamates in good yields.
