143771-37-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143771-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,7 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143771-37:
(8*1)+(7*4)+(6*3)+(5*7)+(4*7)+(3*1)+(2*3)+(1*7)=133
133 % 10 = 3
So 143771-37-3 is a valid CAS Registry Number.

Enantioselective synthesis of 2,2-dialkyltetrahydropyran-3-ones via the asymmetric Michael addition reaction using chiral imines

Desmaele,Pain,D'Angelo

, p. 863 - 866 (1992)

Addition of chiral imine 8 derived from 2-methyltetrahydropyran-3-one 7 and R-(+)-1-phenylethylamine, to methyl acrylate led to adduct (S)-9 with a good yield and an excellent stereoselectivity.
