Check Digit Verification of cas no

The CAS Registry Mumber 197721-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,2 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197721-29:
(8*1)+(7*9)+(6*7)+(5*7)+(4*2)+(3*1)+(2*2)+(1*9)=172
172 % 10 = 2
So 197721-29-2 is a valid CAS Registry Number.

An asymmetric aldol - Ring-closing metathesis strategy for the enantioselective construction of oxygen heterocycles: An efficient approach to the enantioselective synthesis of (+)-laurencin

Crimmins, Michael T.,Choy, Allison L.

, p. 5653 - 5660 (2007/10/03)

A strategy is described for the enantioselective construction of medium- ring cyclic ethers by merging the asymmetric aldol addition of glycolates with a ring-closing metathesis reaction. Cyclic ethers of seven-, eight-, and nine-membered rings are readil
