Check Digit Verification of cas no

The CAS Registry Mumber 193557-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,5,5 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 193557-42:
(8*1)+(7*9)+(6*3)+(5*5)+(4*5)+(3*7)+(2*4)+(1*2)=165
165 % 10 = 5
So 193557-42-5 is a valid CAS Registry Number.

A simple method to polyhydroxylated olefinic molecules using ring-closing olefin metathesis

Chang, Sukbok,Grubbs, Robert H.

, p. 4757 - 4760 (1997)

This paper describes the ring-closing metathesis of silyl ether connected dienes using molybdenum and ruthenium alkylidene catalysts. The cyclizations proceed to afford the corresponding cyclic silyloxy olefins in good to excellent yields. Subsequent oxid

Oligocyclopropane structural units from cationic intermediates

Taylor, Richard E.,Conrad Engelhardt,Yuan, Haiqing

, p. 1257 - 1260 (2008/02/09)

(matrix presented) syn-and anti-bis-cyclopropanes have been efficiently prepared through two distinct routes via the trapping of cyclopropylcarbinyl cationic intermediates. A ring-closing olefin metathesis for the formation of the necessary allylsilane pr
