187099-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187099-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,0,9 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 187099-53:
(8*1)+(7*8)+(6*7)+(5*0)+(4*9)+(3*9)+(2*5)+(1*3)=182
182 % 10 = 2
So 187099-53-2 is a valid CAS Registry Number.

A concise synthesis of 7-substituted indoles
Kondo, Yoshinori,Kojima, Satoshi,Sakamoto, Takao
, p. 2741 - 2746 (2007/10/03)
7-Substituted indoles were synthesized by the basic cyclization of 6-substituted tert-butyl 2-(trimethylsilyiethynyl)phenylcarbamates which were derived by the lithiation of tert-butyl 2- (trimethylsilylethynyl)phenylcarbamate and the subsequent reaction with electrophiles.
