Check Digit Verification of cas no

The CAS Registry Mumber 80879-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,7 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80879-20:
(7*8)+(6*0)+(5*8)+(4*7)+(3*9)+(2*2)+(1*0)=155
155 % 10 = 5
So 80879-20-5 is a valid CAS Registry Number.

Studies on the Pinacol Coupling Reaction

Mundy, Bradford P.,Srinivasa, Ramanujan,Kim, Youseung,Dolph, Thomas,Warnet, Ronald J.

, p. 1657 - 1661 (2007/10/02)

The mixed pinacol coupling reaction has been carefully analyzed.Although a trend toward statistical distribution of products can be found, it is observed that true statistical distributions are rarely observed.Ring-size and alkyl substituent effects are examined.A through-space heteroatom influence on coupling is noted.By use of (R)-(+)-3-methylcyclohexanone, a very specific effect of coupling conditions on product stereochemistry is observed.
