Check Digit Verification of cas no

The CAS Registry Mumber 81803-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81803-32:
(7*8)+(6*1)+(5*8)+(4*0)+(3*3)+(2*3)+(1*2)=119
119 % 10 = 9
So 81803-32-9 is a valid CAS Registry Number.

REGIOSELECTIVE DIELS-ALDER REACTIONS. THE NITRO GROUP AS A REGIOCHEMICAL CONTROL ELEMENT

Ono, Noboru,Miyake, Hideyoshi,Kamimura, Akio,Kaji, Aritsune

, p. 1929 - 1936 (2007/10/02)

The sequence of the Diels-Alder reaction of α-nitroalkenes with diens and subsequent denitration with Bu3SnH provides a new method for the regioselective construction of cyclohexene derivatives.

Regioselective Construction of Cyclohexene Derivatives by Diels-Alder Reactions of Nitro-olefins with Dienes and Subsequent Denitration with Tributyltin Hydride

Ono, Noboru,Miyake, Hideyoshi,Kaji, Aritsune

, p. 33 - 34 (2007/10/02)

The nitro-group in the Diels-Alder adducts of nitro-olefins with dienes is replaced by hydrogen on treatment with tributyltin hydride, which offers a new method for the regioselective construction of cyclohexene derivatives.
