Check Digit Verification of cas no

The CAS Registry Mumber 1041994-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,1,9,9 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1041994-65:
(9*1)+(8*0)+(7*4)+(6*1)+(5*9)+(4*9)+(3*4)+(2*6)+(1*5)=153
153 % 10 = 3
So 1041994-65-3 is a valid CAS Registry Number.

The first synthesis of a 12-membered macrolide natural product via a RCM protocol: determination of absolute stereochemistry

Krishna, Palakodety Radha,Srinivas, Ravula

, p. 1153 - 1160 (2008/09/19)

The first synthesis of (10S,12R)-10-hydroxy-12-methyl-1-oxacyclododecane-2,5-dione and its C12 epimer is reported, thereby assigning the absolute stereochemistry of the natural product. The strategy utilizes a syn selective reduction, Yamaguchi esterification, and ring-closing metathesis as the key steps.
