Check Digit Verification of cas no

The CAS Registry Mumber 143381-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,8 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143381-58:
(8*1)+(7*4)+(6*3)+(5*3)+(4*8)+(3*1)+(2*5)+(1*8)=122
122 % 10 = 2
So 143381-58-2 is a valid CAS Registry Number.

Highly Stereodivergent Approach to Both Enantiomers of 4-Substituted β-Lactams via Diastereofacially Controlled Addition of Enolates of t-Butyl Acetate to a Chiral Imine

Shimizu, Makoto,Ukaji, Yutaka,Tanizaki, Junko,Fujisawa, Tamotsu

, p. 1349 - 1352 (2007/10/02)

Addition of lithium or triisopropoxytitanium enolate derived from t-butyl acetate to a chiral imine possessing dioxolane ring as a chiral auxiliary gave (3S)-β-amino ester exclusively, whereas chlorozinc enolate underwent re-facial attack to give (3R)-iso
