Check Digit Verification of cas no

The CAS Registry Mumber 812643-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,2,6,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 812643-99:
(8*8)+(7*1)+(6*2)+(5*6)+(4*4)+(3*3)+(2*9)+(1*9)=165
165 % 10 = 5
So 812643-99-5 is a valid CAS Registry Number.

Stereoelective polymerization of D,L-lactide using N-heterocyclic carbene based compounds

Jensen, Tryg R.,Breyfogle, Laurie E.,Hillmyer, Marc A.,Tolman, William B.

, p. 2504 - 2505 (2004)

A new Zn alkoxide catalyst supported by an N-heterocyclic carbene rapidly polymerizes D,L-lactide (D.L-LA) to heterotactic enriched poly(lactide) (PLA), while the free carbene and analogs instead yield highly isotactic enriched PLA.
