Check Digit Verification of cas no

The CAS Registry Mumber 74746-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,4 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74746-16:
(7*7)+(6*4)+(5*7)+(4*4)+(3*6)+(2*1)+(1*6)=150
150 % 10 = 0
So 74746-16-0 is a valid CAS Registry Number.

Electrocyclic Reactions of Protonated Chalcones: Synthesis of 3-Arylindan-1-ones

McDonald, Edward,Smith, Paul

, p. 837 - 842 (2007/10/02)

A series of ortho-bromochalcones has been prepared and each has been heated and irradiated in strong acid.In most cases a four-electron electrocyclic reaction occurred preferentially to give 3-arylindan-1-ones in good yield.The acrylchalcone 4'-methoxy-3,
