Check Digit Verification of cas no

The CAS Registry Mumber 745015-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,5,0,1 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 745015-92:
(8*7)+(7*4)+(6*5)+(5*0)+(4*1)+(3*5)+(2*9)+(1*2)=153
153 % 10 = 3
So 745015-92-3 is a valid CAS Registry Number.

A Stereoselective Approach to 2,6-Disubstituted Tetrahydropyrans by Conjugate Addition Reactions of Vinyl Sulfones

Craig,Edwards,Muldoon

, p. 1318 - 1320 (2007/10/03)

A highly stereoselective synthesis of cis-2,6-disubstituted tetrahydropyrans from functionalised 5-hexen-1-ols has been developed. Free radical addition of para-toluenesulfonyl iodide to the hexenol and DBU-mediated elimination of HI from the intermediate β-iodosulfones gives vinyl sulfones: subsequent conjugate addition of the potassium alkoxide leads to a highly stereoselective (≥30:1) cyclisation.
