Check Digit Verification of cas no

The CAS Registry Mumber 116127-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,2 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 116127-33:
(8*1)+(7*1)+(6*6)+(5*1)+(4*2)+(3*7)+(2*3)+(1*3)=94
94 % 10 = 4
So 116127-33-4 is a valid CAS Registry Number.

STEREOSELECTIVE KINETIC PROTONATION OF CHIRAL γ-LACTONE ENOLATES

Takano, Seiichi,Kudo, Junko,Takahashi, Michiyasu,Ogasawara, Kunio

, p. 2405 - 2408 (1986)

When lithium enolates generated from five chiral α,γ-disubstituted γ-lactones are treated with proton sources, formation of the α,γ-syn epimers always predominates over the α,γ-anti epimers in ratios of 10.2-2.9:1.Higher syn/anti ratios are obtained via silyl enolates in some cases.Chirality discrimination by chiral proton source is also observed in particular cases.
