Check Digit Verification of cas no

The CAS Registry Mumber 408305-22-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,3,0 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 408305-22:
(8*4)+(7*0)+(6*8)+(5*3)+(4*0)+(3*5)+(2*2)+(1*2)=116
116 % 10 = 6
So 408305-22-6 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 (2001)

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.
