Check Digit Verification of cas no

The CAS Registry Mumber 91388-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,8 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91388-49:
(7*9)+(6*1)+(5*3)+(4*8)+(3*8)+(2*4)+(1*9)=157
157 % 10 = 7
So 91388-49-7 is a valid CAS Registry Number.

1,7-Electrocyclisation and Carbene Reactions of o-Alkenylaryldiazoalkanes: The Effect of Alkene Configuration on the Mode of Reaction

Munro, David P.,Sharp, John T.

, p. 849 - 858 (2007/10/02)

The 1,7-8?-electron electrocyclisation of o-alkenylaryldiazoalkanes (1) to give 1H-2,3-benzodiazepines (3) takes place readily for substrates with a cis-hydrogen atom at the cyclisation site, but is blocked by phenyl or methyl groups at that position.Such
