Check Digit Verification of cas no

The CAS Registry Mumber 1038860-88-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,8,8,6 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1038860-88:
(9*1)+(8*0)+(7*3)+(6*8)+(5*8)+(4*6)+(3*0)+(2*8)+(1*8)=166
166 % 10 = 6
So 1038860-88-6 is a valid CAS Registry Number.

Highly effective vinylogous Mukaiyama-Michael reaction catalyzed by silyl methide species generated from 1,1,3,3-tetrakis(trifluoromethanesulfonyl)propane

supporting information; experimental part, p. 1259 - 1265 (2010/04/29)

(Chemical Equation Presented) Silyl methide species in situ generated from 1,1,3,3-tetrakis(trifluoromethanesulfonyl)propane (Tf2CHCH 2CHTf2) performed as an excellent acid catalyst for the vinylogousMukaiyama-Michael reaction of α,β-unsaturated ketones with 2-silyloxyfurans. Notably, the required loading of Tf2CHCH 2CHTf2 to obtain the 1,4-adducts in reasonable yield was significantly low (from 0.05 to 1.0 mol%). This carbon acid-mediatedVMMreaction provides a powerful synthetic methodology to construct highly substituted γ-butenolide structure. 2010 American Chemical Society.
