Check Digit Verification of cas no

The CAS Registry Mumber 198697-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,6,9 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 198697-33:
(8*1)+(7*9)+(6*8)+(5*6)+(4*9)+(3*7)+(2*3)+(1*3)=215
215 % 10 = 5
So 198697-33-5 is a valid CAS Registry Number.

Geminal Acylation with Methyl-Substituted Analogues of 1,2-Bis[(trimethylsilyl)oxy]cyclobutene

Crane, Sheldon N.,Jenkins, Tracy J.,Jean Burnell

, p. 8722 - 8729 (1997)

BF3·Et2O-catalyzed geminal acylation of ketones and acetals with 3-methyl-1,2-bis[(trimethylsilyl)oxy)]cyclobutene (3) provided methylcyclopentanediones in yields that ranged from 40 to 94%. The best substrates were unhindered cycloh
