Check Digit Verification of cas no

The CAS Registry Mumber 65655-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,5 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65655-78:
(7*6)+(6*5)+(5*6)+(4*5)+(3*5)+(2*7)+(1*8)=159
159 % 10 = 9
So 65655-78-9 is a valid CAS Registry Number.

Deamination Reactions, 45. Decomposition of 1-Arylcyclopropanediazonium Ions

Kirmse, Wolfgang,Rode, Jutta

, p. 3694 - 3703 (2007/10/02)

1-Arylcyclopropanediazonium ions have been generated by alkaline cleavage of the analogous nitrosocarbamates in methanol.With increasing ?-donor capacity of the aryl groups, retention of the three-membered ring was enhanced while the stereoselectivity (as probed with the aid of 2-D labels) was diminished or entirely lost (4-methoxyphenyl).Where applicable, the stereoselectivity of ring opening is inferior to that of nucleophilic displacement.The data may be interpreted in terms of competing reactions (ks, kc, kΔ) of the cyclopropanediazonium ions.
