Check Digit Verification of cas no

The CAS Registry Mumber 1228797-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,7,9 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1228797-32:
(9*1)+(8*2)+(7*2)+(6*8)+(5*7)+(4*9)+(3*7)+(2*3)+(1*2)=187
187 % 10 = 7
So 1228797-32-7 is a valid CAS Registry Number.

Natural α-amino acid l-lysine-catalyzed knoevenagel condensations of α,β-unsaturated aldehydes and 1,3-dicarbonyl compounds

He, Yan-Hong,Hu, Ying,Guan, Zhi

experimental part, p. 1617 - 1628 (2011/06/21)

Knoevenagel condensations of α,β-unsaturated aldehydes and 1,3-dicarbonyl compounds were catalyzed by primary natural amino acid L-lysine. The reactions were carried out at room temperature in dimethylsulfoxide. It provides a facile entry to a wide variety of α,β,γ,δ- unsaturated dicarbonyl compounds.
