Check Digit Verification of cas no

The CAS Registry Mumber 14046-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,4 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14046-19:
(7*1)+(6*4)+(5*0)+(4*4)+(3*6)+(2*1)+(1*9)=76
76 % 10 = 6
So 14046-19-6 is a valid CAS Registry Number.

A convenient method for the synthesis of activated N-methylcarbamates

Konakahara,Ozaki,Sato,Gold

, p. 103 - 106 (1993)

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.
