Check Digit Verification of cas no

The CAS Registry Mumber 39981-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,8 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39981-72:
(7*3)+(6*9)+(5*9)+(4*8)+(3*1)+(2*7)+(1*2)=171
171 % 10 = 1
So 39981-72-1 is a valid CAS Registry Number.

, p. 348 - 351 (2007/10/02)

Secondary reactions with the addition of the alcohol radicals to the ketyl radical of the phenalenone were observed during the irradiation of phenalenone in alcohols.In the presence of oxygen hydroxyphenalenones are formed in addition to the α-hydroxyalkyl derivatives.The dimerization and disproportionation processes are ineffective in the ketyl radicals of phenalenone.
