Check Digit Verification of cas no

The CAS Registry Mumber 1397692-01-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,6,9 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1397692-01:
(9*1)+(8*3)+(7*9)+(6*7)+(5*6)+(4*9)+(3*2)+(2*0)+(1*1)=211
211 % 10 = 1
So 1397692-01-1 is a valid CAS Registry Number.

PROCESS FOR PRODUCING v-COELENTERAZINE COMPOUNDS

-

Page/Page column 21-22, (2012/09/22)

A simple process for producing v-coelenterazine compounds has been desired. Described is a process for producing a v-coelenterazine compound represented by general formula (II) comprising (1) the step of reacting a compound of general formula (VIII) with a methyltriphenylphosphonium salt in the presence of a base to give a compound represented by general formula (IX), (2) the step of performing a ring-closing metathesis reaction on any one selected from the group consisting of the compound represented by general formula (IX) and a compound of general formula (X) which is the compound of general formula (IX) wherein the amino is protected with R5, and then deprotecting R4 and, if any, R5 to give a v-coelenteramine compound represented by general formula (XIV), and (3) the step of reacting the compound of general formula (XIV) with a compound represented by general formula (XV) to give the compound of general formula (II).
