Check Digit Verification of cas no

The CAS Registry Mumber 696619-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,6,6,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 696619-49:
(8*6)+(7*9)+(6*6)+(5*6)+(4*1)+(3*9)+(2*4)+(1*9)=225
225 % 10 = 5
So 696619-49-5 is a valid CAS Registry Number.

Nucleophilic substitution in 4-bromo-5-nitrophthalodinitrile: IX. Synthesis of 4-(morpholin-4-yl)-5-aryloxyphthalodinitriles and copper phthalocyanines based thereon

Fedotova,Maizlish,Shaposhnikov,Filimonov,Abramov

experimental part, p. 1018 - 1023 (2011/04/16)

Nucleophilic aromatic substitution of bromine in 4-bromo-5- nitrophthalodinitrile with the morpholine residue and the subsequent substitution of nitro group with the aryloxy one yielded 4-morpholyl-5- aryloxyphthalodinitriles. From these substances octasubstituted copper phthalocyanines were synthesized, and their physicochemical properties were studied.
