Check Digit Verification of cas no

The CAS Registry Mumber 1628779-53-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,8,7,7 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1628779-53:
(9*1)+(8*6)+(7*2)+(6*8)+(5*7)+(4*7)+(3*9)+(2*5)+(1*3)=222
222 % 10 = 2
So 1628779-53-2 is a valid CAS Registry Number.

On-water synthesis of dipyrromethanes via bis-hetero-diels-alder reaction of azo- and nitrosoalkenes with pyrrole

Pereira, Nelson A. M.,Lopes, Susana M. M.,Lemos, Américo,Pinho E Melo, Teresa M. V. D.

, p. 423 - 427 (2014)

An unprecedented one-pot approach to 5-substituted dipyrromethanes based on the hetero-Diels-Alder reaction of azo- and nitrosoalkenes is described. The on-water reaction conditions led to the target compounds in higher yields with significantly shorter r
