Check Digit Verification of cas no

The CAS Registry Mumber 135746-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,4 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135746-47:
(8*1)+(7*3)+(6*5)+(5*7)+(4*4)+(3*6)+(2*4)+(1*7)=143
143 % 10 = 3
So 135746-47-3 is a valid CAS Registry Number.

The Scope and Limitations of Intramolecular Radical Cyclizations of Acylsilanes with Alkyl, Aryl, and Vinyl Radicals

Chang, Sheng-Yueh,Jiaang, Weir-Torn,Cherng, Chaur-Donp,Tang, Kuo-Hsiang,Huang, Chih-Hao,Tsai, Yeun-Min

, p. 9089 - 9098 (2007/10/03)

5-Exo cyclizations of primary and secondary radicals with acylsilanes successfully give cyclopentyl silyl ethers. The corresponding 6-exo cyclizations are sensitive to changes of the size of silyl groups. Secondary radicals undergo 6-exo cyclizations with

Regioselectivity in and Annulation Reactions of Bis(trimethylsilyl) Enol Ethers with Acylsilane Dicarbonyl Dielectrophiles

Molander, Gary A.,Siedem, Christopher S.

, p. 130 - 138 (2007/10/02)

A number of 1,4- and 1,5-acylsilane dicarbonyl compounds were synthesized using Corey-Brook dithiane methods.These dicarbonyl substrates were annulated with the bis(trimethylsilyl) enol ether of methyl acetoacetate in the presence of TMSOTf, affording bic
