Check Digit Verification of cas no

The CAS Registry Mumber 1251850-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,1,8,5 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1251850-81:
(9*1)+(8*2)+(7*5)+(6*1)+(5*8)+(4*5)+(3*0)+(2*8)+(1*1)=143
143 % 10 = 3
So 1251850-81-3 is a valid CAS Registry Number.

Enantioselective synthesis of β-hydroxy ketones from heterocyclic aldehydes in water catalyzed by a recyclable organocatalyst bearing an ionic liquid moiety

Siyutkin,Kucherenko,Zlotin

, p. 1899 - 1902 (2009)

The aldol reactions of cyclic (heterocyclic) ketones and heterocyclic aldehydes catalyzed by (4R,S)-4-hydroxyproline modified with a ionic liquid moiety proceed with high yields and diastereo- and enantioselectivity in the presence of water. The catalyst
