Check Digit Verification of cas no

The CAS Registry Mumber 115692-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,6,9 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 115692-92:
(8*1)+(7*1)+(6*5)+(5*6)+(4*9)+(3*2)+(2*9)+(1*2)=137
137 % 10 = 7
So 115692-92-7 is a valid CAS Registry Number.

Lewis Acid Promoted Condensation of Allylalkoxysilanes with Carbonyl Co+pounds. Synthesis of Tetrahydropyrans

Wei, Z. Y.,Wang, D.,Li, J. S.

, p. 5768 - 5774 (2007/10/02)

Allylalkoxysilanes 1 condense with aldehydes under Lewis acid conditions to give cis-2,4,6-trisubstituted tetrahydropyrans 3 or the homoallylic alcohols 2.Factors affecting the reaction have been examined.The enantioselective synthesis of 2 using optically active 1 has also been studied.The reaction is applied to the enantioselective synthesis of (6'-methyl-2'-tetrahydropyranyl)acetic acid (11), a natural compound that has been isolated from the glandular secretion of the civet cat.
