Check Digit Verification of cas no

The CAS Registry Mumber 121406-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,0 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121406-64:
(8*1)+(7*2)+(6*1)+(5*4)+(4*0)+(3*6)+(2*6)+(1*4)=82
82 % 10 = 2
So 121406-64-2 is a valid CAS Registry Number.

NEW METHODOLOGY FOR C-4 SUBSTITUTION AND SULPHOXIDE DE-OXYGENATION REACTIONS IN CEPH-3-EMS

Bremner, David H.,Ringan, Neil S.,Smith, Alistair D. M.

, p. 6687 - 6690 (2007/10/02)

Addition of Michael acceptors to the C-4 position in ceph-3-ems followed by oxidation, de-esterification, and de-carboxylation results in the formation of new 4-monosubstituted ceph-3-ems; an unusually mild de-oxygenation process for ceph-2-em sulphoxides is also described.
