Check Digit Verification of cas no

The CAS Registry Mumber 117659-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,5 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117659-29:
(8*1)+(7*1)+(6*7)+(5*6)+(4*5)+(3*9)+(2*2)+(1*9)=147
147 % 10 = 7
So 117659-29-7 is a valid CAS Registry Number.

Regio- and Stereo-selective Synthesis of β-Sulphonyl-α,β-Unsaturated Carbonyl Compounds via an Iodosulphonylation-Dehydroiodination Raction

Najera, Carmen,Baldo, Beatriz,Yus, Miguel

, p. 1029 - 1032 (2007/10/02)

α,β-Unsaturated carbonyl compounds underwent regiospecific iodosulphonylation with toluene-p-sulphonyl iodide or sodium toluene-p-sulphinate and iodine to afford products (2), which were stereoselectively dehydroiodinated by triethylamine to give β-sulphonyl derivatives (3).The reactivity of compounds (3) as cationic β-acylvinyl equivalents, tested with amines or thiophenol, gave compounds (4) resulting from a displacement reaction.
