Check Digit Verification of cas no

The CAS Registry Mumber 29203-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,2,0 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29203-99:
(7*2)+(6*9)+(5*2)+(4*0)+(3*3)+(2*9)+(1*9)=114
114 % 10 = 4
So 29203-99-4 is a valid CAS Registry Number.

Total syntheses of cis-cyclopropane fatty acids: Dihydromalvalic acid, dihydrosterculic acid, lactobacillic acid, and 9,10-methylenehexadecanoic acid

Shah, Sayali,White, Jonathan M.,Williams, Spencer J.

, p. 9427 - 9438 (2014)

cis-Cyclopropane fatty acids (cis-CFAs) are widespread constituents of the seed oils of subtropical plants, membrane components of bacteria and protozoa, and the fats and phospholipids of animals. We describe a systematic approach to the synthesis of enan

An Unexpected Reversal of Fluorine Substituent Effects in the Biomethylenation of Two Positional Isomers: A Serendipitous Discovery

Buist, Peter H.,Pon, Robert A.

, p. 6240 - 6241 (2007/10/02)

The mechanism of biological cyclopropyl fatty acid biosynthesis as it occurs in Lactobacillus plantarum has been probed using fluorine substituent effects.It has been shown that the pattern of rate retardations induced by homoallylic fluorine substitution is numerically the same but opposite in sense for two series of olefinic fatty acid substrates bearing the double bond at either the 9- or the 11-position.
