Check Digit Verification of cas no

The CAS Registry Mumber 138290-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,9 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138290-85:
(8*1)+(7*3)+(6*8)+(5*2)+(4*9)+(3*0)+(2*8)+(1*5)=144
144 % 10 = 4
So 138290-85-4 is a valid CAS Registry Number.

Cyclopropenation of alkylidene carbenes derived from α-silyl ketones

Li, Jingwei,Sun, Chunrui,Lee, Daesung

supporting information; experimental part, p. 6640 - 6641 (2010/07/04)

A new cyclopropanation reaction involving Cα-Si bond insertion of alkylidene carbenes derived from α-silyl ketones has been developed. This unprecedented alkylidene carbene reactivity features excellent selectivity for insertion into Cα-Si bonds rather than insertion into Cγ-H bonds or addition to,δ-double or -triple bonds. The selectivity trend clearly indicates that the α-oxygen in the tether significantly promotes Cγ-H insertion, although the Cα-Si bond insertion still competes effectively.

Ethyl Cyanoformate/Hydrogen Peroxide and Related Combination Systems, Novel Epoxidizing Systems of Olefins

Masaki, Yukio,Miura, Tsuyoshi,Mukai, Isao,Itoh, Akichika,Oda, Hirohisa

, p. 1937 - 1940 (2007/10/02)

A combination system of ethyl cyanoformate and hydrogen peroxide was found to epoxidize olefins in a stereospecific manner at room temperature.Asymmetric epoxidation was observed with menthyl cyanoformate/hydrogen peroxide system.
