909-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909-63-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 909-63:
(5*9)+(4*0)+(3*9)+(2*6)+(1*3)=87
87 % 10 = 7
So 909-63-7 is a valid CAS Registry Number.

CONDENSATION OF VILSMEIER COMPLEXES WITH HETEROCYCLIC COMPOUNDS. SYNTHESIS OF CARBOCYANINES
Makin, S. M.,Pomogaev, A. I.
, p. 1916 - 1918 (2007/10/02)
Carbocyanine dyes are formed in the reaction of the quaternary salts of heterocyclic bases containing an active methyl group with the complexes of carboxamides and phosphorus oxychloride.A series of carbocyanines were synthesized, including those containing various substituents at the meso position of the trimethine chain.
