Check Digit Verification of cas no

The CAS Registry Mumber 1621478-66-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,4,7 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1621478-66:
(9*1)+(8*6)+(7*2)+(6*1)+(5*4)+(4*7)+(3*8)+(2*6)+(1*6)=167
167 % 10 = 7
So 1621478-66-7 is a valid CAS Registry Number.

Rhodium(III)-catalyzed, C-H activated annulation to form isocoumarins and α-pyrones using the O-N bond as an internal oxidant

Li, Xing Guang,Liu, Kai,Zou, Gang,Liu, Pei Nian

, p. 1496 - 1500 (2014)

A mild, efficient and regioselective C-H activation-based intermolecular redox-neutral annulation of O-benzoylhydroxylamines and internal alkynes has been achieved. The protocol employs an O-N bond as the internal oxidant and leads to isocoumarins and α-pyrones.
