Check Digit Verification of cas no

The CAS Registry Mumber 66819-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,1 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66819-38:
(7*6)+(6*6)+(5*8)+(4*1)+(3*9)+(2*3)+(1*8)=163
163 % 10 = 3
So 66819-38-3 is a valid CAS Registry Number.

The chiral keto alcohol 6a was prepared from (S)-(+)-carvone.Because two steps in this process gave only modest yields of isolated materials, an alternative route was developed.Racemic keto alcohol 6b was prepared from enedione rac-13a by a more efficient process.
