Check Digit Verification of cas no

The CAS Registry Mumber 136917-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,1 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136917-81:
(8*1)+(7*3)+(6*6)+(5*9)+(4*1)+(3*7)+(2*8)+(1*1)=152
152 % 10 = 2
So 136917-81-2 is a valid CAS Registry Number.

Catalytic Asymmetric Aldol Reaction of the Silyl Enol Ether of Acetic Acid Thioester with Aldehydes Using Chiral Tin(II) Lewis Acid

Kobayashi, Shu,Furuya, Minoru,Ohtsubo, Akihiro,Mukaiyama, Teruaki

, p. 635 - 638 (2007/10/02)

Catalytic asymmetric aldol reaction of the silyl enol ether derived from S-ethyl ethanethioate with achiral aldehydes is carried our by using chiral diamine-coordinated tin(II) triflate to afford the corresponding aldol-type adducts, α-unsubstituted β-hydroxy thioesters, in good yields with high ees.
