Check Digit Verification of cas no
The CAS Registry Mumber 108262-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,6 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108262-52:
(8*1)+(7*0)+(6*8)+(5*2)+(4*6)+(3*2)+(2*5)+(1*2)=108
108 % 10 = 8
So 108262-52-8 is a valid CAS Registry Number.

, p. 1583 - 1586 (2007/10/02)
Diaryl- and Alkylaryl-substituted 2-aminofurancarboxylates have been obtained as Schiff bases 5,6 by cyclization of 2-ethoxycarbonyl-4-oxonitriles 3,4; which result from hydrogen cyanide addition to ethyl α-acylcinnamates 1,2.
