Check Digit Verification of cas no

The CAS Registry Mumber 1620644-18-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,6,4 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1620644-18:
(9*1)+(8*6)+(7*2)+(6*0)+(5*6)+(4*4)+(3*4)+(2*1)+(1*8)=139
139 % 10 = 9
So 1620644-18-9 is a valid CAS Registry Number.

Synthesis of 3,3-disubstituted-2,3-dihydroazanaphthoquinones via simultaneous alkyne oxidation and nitrile hydration of ortho- alkynylarenenitriles

Sakthivel, Karuppusamy,Srinivasan, Kannupal

, p. 6440 - 6446 (2014)

o-Alkynylarenenitriles when heated with Pd(OAc)2/H 2O/(±)-CSA in DMSO undergo simultaneous alkyne oxidation and nitrile hydration to give 3-aryl-3-hydroxy-2,3-dihydroazanaphthoquinones. Upon treatment with (±)-CSA, these compounds fo
