Check Digit Verification of cas no
The CAS Registry Mumber 16947-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,4 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16947-69:
(7*1)+(6*6)+(5*9)+(4*4)+(3*7)+(2*6)+(1*9)=146
146 % 10 = 6
So 16947-69-6 is a valid CAS Registry Number.

A convenient method for the synthesis of activated N-methylcarbamates
Konakahara,Ozaki,Sato,Gold
, p. 103 - 106 (2007/10/02)
An investigation of methods to efficiently prepare activated N-methylcarbamates is reported. N-(Methylcarbamoyloxy)succinimide (3a), aryl N-methylcarbamates 3b-d and 2,2,2-trifluoro-1-(trifluoromethyl)ethyl N-methylcarbamate (3e) have been prepared in 70-80% yields from the corresponding chloroformates 5a-e, which were prepared as crystalline solids by the condensation of trichloromethylchloroformate (1) or bis(trichloromethyl)carbonate (2) with hydroxy compounds 4a-e in high yields.
