Check Digit Verification of cas no

The CAS Registry Mumber 1643565-84-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,5,6 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1643565-84:
(9*1)+(8*6)+(7*4)+(6*3)+(5*5)+(4*6)+(3*5)+(2*8)+(1*4)=187
187 % 10 = 7
So 1643565-84-7 is a valid CAS Registry Number.

, p. 5847 - 5855 (2014/08/05)

A highly diastereoselective and enantioselective method for the asymmetric desymmetrization of 4,4-disubstituted cyclohexadienones using the Michael addition reaction of malonates under catalysis with the primary amine-thiourea conjugate catalyst and PPY at high pressure was developed. This journal is the Partner Organisations 2014.
