186375-61-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 186375-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,3,7 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 186375-61:
(8*1)+(7*8)+(6*6)+(5*3)+(4*7)+(3*5)+(2*6)+(1*1)=171
171 % 10 = 1
So 186375-61-1 is a valid CAS Registry Number.

Protection of a protecting group: Preparation of stable N-silylated t-butyl carbamates
Roby, Johanne,Voyer, Normand
, p. 191 - 194 (1997)
The practical preparation of N-silylated carbamates (typified by 1) is reported. These compounds are synthesized in high yields by treating N-t-Boc-protected primary amines with silyl triflate reagents in dichloromethane in the presence of triethylamine.
