Check Digit Verification of cas no
The CAS Registry Mumber 37746-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,4 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37746-78:
(7*3)+(6*7)+(5*7)+(4*4)+(3*6)+(2*7)+(1*8)=154
154 % 10 = 4
So 37746-78-4 is a valid CAS Registry Number.

Stereoselective halo-succinimide mediated γ-halogenations of substituted α-trialkylsilyl-β,γ-unsaturated esters
Fealy, Lisa M.,Jennings, Michael P.
, (2020)
The halogenation of various α-ester allylsilanes with halo-succinimides (NXS, X = Cl, Br, and I) has been investigated. It has been shown that these reactions readily allow for good yields and excellent diastereoselectivities (up to >20:1) for a series of α-ester allylsilanes and halo-succinimide reagents, thereby providing a straightforward approach of preparing γ-halo-(E)-α,β-unsaturated esters.
