Check Digit Verification of cas no
The CAS Registry Mumber 1622-15-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1622-15:
(6*1)+(5*6)+(4*2)+(3*2)+(2*1)+(1*5)=57
57 % 10 = 7
So 1622-15-7 is a valid CAS Registry Number.

Triphenyl verdazyl radicals' reactivity with alkyne carboxylates as a synthetic route to 1-(phenyldiazenyl)isoquinoline-3,4-dicarboxylates
Bancerz, Matthew,Prack, Ernest,Georges, Michael K.
supporting information; experimental part, p. 4026 - 4029 (2012/08/13)
A series of 1-(phenyldiazenyl)isoquinoline-3,4-dicarboxylates are synthesized by a unique reaction of triphenyl verdazyl radical with di-substituted electron deficient alkyne carboxylates. This transformation allows for the quick synthesis of this class of compounds in just three steps starting from a hydrazone. A radical mechanism that is consistent for the substitution patterns observed in the series of compounds made is proposed. The final product is obtained by a subsequent retro-Diels-Alder reaction.
