Check Digit Verification of cas no

The CAS Registry Mumber 200337-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,3,3 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200337-71:
(8*2)+(7*0)+(6*0)+(5*3)+(4*3)+(3*7)+(2*7)+(1*1)=79
79 % 10 = 9
So 200337-71-9 is a valid CAS Registry Number.

Uchiyama, Masahiko,Katoh, Nobuo,Mimura, Rio,Yokota, Naoko,Shimogaichi, Yuki,Shimazaki, Makoto,Ohta, Akihiro

, p. 3467 - 3474 (2007/10/03)

Asymmetric reduction of symmetrical diacetylaromatics (1a, 1b, and 1d- g) with baker's yeast (Saccharomyces cerevisiae) provided the corresponding alcohols of high enantiomeric purity. By choosing appropriate reaction conditions, the products were preferentially the monoalcohols over the diols.
