89774-48-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89774-48-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,7 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89774-48:
(7*8)+(6*9)+(5*7)+(4*7)+(3*4)+(2*4)+(1*8)=201
201 % 10 = 1
So 89774-48-1 is a valid CAS Registry Number.

1,2,2,2-Tetrachloroethyl Carbamates: Versatile Intermediates for the Synthesis of N-Nitrosoureas
Barcelo, Gerard,Senet, Jean-Pierre,Sennyey, Gerard
, p. 1027 - 1029 (2007/10/02)
1,2,2,2-Tetrachloroethyl carbamates 3 were prepared by the reaction of 1,2,2,2-tetrachloroethyl carbonochloridate with amines.Carbamates 3 were then nitrosated and reacted with amines to yield N-nitrosoureas.
