Check Digit Verification of cas no

The CAS Registry Mumber 98302-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98302-76:
(7*9)+(6*8)+(5*3)+(4*0)+(3*2)+(2*7)+(1*6)=152
152 % 10 = 2
So 98302-76-2 is a valid CAS Registry Number.

Pyrolysis and Photolysis of the N-Oxides of Protopines and Hexahydrobenzophenanthridines. Syntheses of the Secoberbines and Benzophenanthridines

Iwasa, Kinuko,Sugiura, Makiko,Takao, Narao

, p. 998 - 1008 (2007/10/02)

Pyrolysis and photolysis of the N-oxides of the protopines 9 and 16 produces the ring-enlarged compounds 10 and 17, whose reduction with zinc in acetic acid leads to the secoberbines (+/-)-corydalisol (11) and (+/-)-hypecorine (12) from 9, and the corresponding analogs (18 and 19) from 16.Pyrolysis of (+)-chelidonine N-oxide (24) generates dihydrosanguinarine (22).Keywords - pyrolysis; photolysis; N-oxide; protopine; sanguinarine; corydalisol; hypecorine
