Check Digit Verification of cas no

The CAS Registry Mumber 51769-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,6 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51769-31:
(7*5)+(6*1)+(5*7)+(4*6)+(3*9)+(2*3)+(1*1)=134
134 % 10 = 4
So 51769-31-4 is a valid CAS Registry Number.

Enzyme-triggered enantioconvergent transformation of haloalkyl epoxides

Mayer, Sandra F.,Steinreiber, Andreas,Orru, Romano V. A.,Faber, Kurt

, p. 4537 - 4542 (2007/10/03)

Biocatalytic hydrolysis of 2,3-disubstituted rac-cis- and rac-trans-haloalkyl epoxides 1a-8a using the epoxide hydrolase activity of whole bacterial cells furnished the corresponding vicinal diols 1b-8b as intermediates; these (spontaneously) underwent ring closure to yield cyclic products 1c-6c through an enzyme-triggered cascade reaction. In particular, cis-configured substrates (1a, 3a, 5a, 7a) were transformed in an enantioconvergent fashion, which resulted in the formation of single stereoisomeric products in 100% des and up to 92% ees from the racemates.

Dihydro- and Tetrahydrofuran Building Blocks from 1,4:3,6-Dianhydrohexitols. 2. Synthesis of Acetal, Alcohol, Diol, Epoxide, Hydrocarbon, and Lactone Pheromones

Paolucci, Claudio,Mazzini, Claudio,Fava, Antonio

, p. 169 - 175 (2007/10/02)

The potential of building blocks 1-3 for synthesis of enantiopure substances is illustrated by their transformation to various insect pheromones featuring functionalities specified in the title.A convenient synthesis of building block 3 from sorbitol is described.
