Check Digit Verification of cas no

The CAS Registry Mumber 1492020-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,2,0,2 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1492020-34:
(9*1)+(8*4)+(7*9)+(6*2)+(5*0)+(4*2)+(3*0)+(2*3)+(1*4)=134
134 % 10 = 4
So 1492020-34-4 is a valid CAS Registry Number.

Preparative access to medicinal chemistry related chiral alcohols using carbonyl reductase technology

Rowan, Andrew S.,Moody, Thomas S.,Howard, Roger M.,Underwood, Toby J.,Miskelly, Iain R.,He, Yanan,Wang, Bo

, p. 1369 - 1381 (2013)

Libraries of highly enantioenriched secondary alcohols in both enantiomeric forms were synthesised by enzymatic reduction of their parent ketones using selectAZyme carbonyl reductase (CRED) technology. Commercially available CREDs were able to reduce a range of substrate classes efficiently and with very high enantioselectivity. Matching substrate classes to small subsets of CREDs enabled the fast development of preparative bioreductions and the rapid generation of 100-1500 mg samples of chiral alcohols in typically >95% ee and the majority in ≥99.0% ee. The conditions for small scale synthesis were then scaled up to 0.5 kg to deliver one of the chiral alcohols, (S)-1-(4-bromophenyl)-2-chloroethanol, in 99.8% ee and 91% isolated yield.
