Check Digit Verification of cas no

The CAS Registry Mumber 537653-10-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,7,6,5 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 537653-10:
(8*5)+(7*3)+(6*7)+(5*6)+(4*5)+(3*3)+(2*1)+(1*0)=164
164 % 10 = 4
So 537653-10-4 is a valid CAS Registry Number.

Facile Biginelli-type reactions catalysed by super acidic ionic liquid under solvent-free conditions

Wang, Liang,Zhou, Min,Chen, Qun,He, Ming-Yang

, p. 712 - 714 (2013/02/23)

[MeC(OH)2]+ClO4-?as a super acidic ionic liquid is an extremely active catalyst for Biginelli-type reactions. The present method is especially effective for the inactive aliphatic aldehydes. The solvent-free conditions, high catalytic activity, wide substrates tolerance and convenient product isolation make the protocol more advantageous.
