Check Digit Verification of cas no

The CAS Registry Mumber 66224-74-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,2 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 66224-74:
(7*6)+(6*6)+(5*2)+(4*2)+(3*4)+(2*7)+(1*4)=126
126 % 10 = 6
So 66224-74-6 is a valid CAS Registry Number.

Syntheses of fused tetrahydro-β-carboline analogues through imide carbonyl activation using BBr3: Evidence for the involvement of fused cyclic N-acyliminium ion intermediate

Mangalaraj, Selvaraj,Selvakumar, Jayaraman,Ramanathan, Chinnasamy Ramaraj

, p. 811 - 819 (2015)

Abstract The fused cyclic N-acyliminium ion generated during the imide carbonyl activation reaction of phenethylphthalimide was confirmed by single crystal X-ray diffraction. The Lewis acid assisted imide carbonyl activation methodology was successfully extended to synthesize fused tetrahydro-β-carboline units from the corresponding N-indolylethylimides.
