Check Digit Verification of cas no

The CAS Registry Mumber 1309761-62-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,7,6 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1309761-62:
(9*1)+(8*3)+(7*0)+(6*9)+(5*7)+(4*6)+(3*1)+(2*6)+(1*2)=163
163 % 10 = 3
So 1309761-62-3 is a valid CAS Registry Number.

Cobalt(I) catalysis in the diastereoselective two-step synthesis of tricyclic systems

Erver, Florian,Hilt, Gerhard,Harms, Klaus

experimental part, p. 972 - 978 (2011/05/07)

The diastereoselective two-step synthesis of heterotricyclic systems is accomplished by regioselective cobalt-catalysed [4+2]- and [4+2+2]-cycloaddition reactions generating cyclohexa-1,4-diene and cycloocta-1,3,6-triene derivatives, and a hetero-Diels-Alder reaction. Thus, a set of selected cyclohexadienes and cyclooctatrienes were reacted with cyclic 1,3-diones and formaldehyde in a Knoevenagel-hetero-Diels-Alder multicomponent reaction to produce a variety of tricyclic products.
