Check Digit Verification of cas no

The CAS Registry Mumber 218268-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,2,6 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 218268-89:
(8*2)+(7*1)+(6*8)+(5*2)+(4*6)+(3*8)+(2*8)+(1*9)=154
154 % 10 = 4
So 218268-89-4 is a valid CAS Registry Number.

Binreduction of (R)-carvone and regioselective baeyer-villiger oxidations: Application to the asymmetric synthesis of cryptophycin fragment A

Varie, David L.,Brennan, John,Briggs, Barbara,Cronin, Jason S.,Hay, David A.,Rieck III, John A.,Zmijewski, Milton J.

, p. 8405 - 8408 (2007/10/03)

Cryptophycin fragment A (1) was prepared in high enantiomeric purity in 10 steps from (R)-carvone. A stereoselective bioreduction of (R)-carvone to neodihydrocarveol and a regioselective Baeyer-Villiger oxidation of cyclohexanone 8 with pertrifluoroacetic acid were employed in this synthesis.
