1355021-25-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1355021-25-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,5,0,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1355021-25:
(9*1)+(8*3)+(7*5)+(6*5)+(5*0)+(4*2)+(3*1)+(2*2)+(1*5)=118
118 % 10 = 8
So 1355021-25-8 is a valid CAS Registry Number.

Tandem migration - Carboalkoxylation of o-isocyanophenyl acetals leading to benzoxazoles
Okitsu, Takashi,Nagase, Kenta,Nishio, Nobuhiko,Wada, Akimori
, p. 708 - 711 (2012/04/04)
An efficient approach to benzoxazoles via tandem migration - carboalkoxylation of o-isocyanophenyl acetals has been developed. Both a Lewis acid and base are essential for this reaction, and the BF3· OEt2/2,4,6-collidine combination
