76619-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76619-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,1 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76619-45:
(7*7)+(6*6)+(5*6)+(4*1)+(3*9)+(2*4)+(1*5)=159
159 % 10 = 9
So 76619-45-9 is a valid CAS Registry Number.

Synthesis of Some Novel Analogues of Phthalein Dyes: Phthal-as-eins
Chamoli, R. P.,Gupta, P. C.
, p. 777 - 779 (2007/10/02)
A number of novel phthalein dyes (V-X) have been synthesised by the condensation of phenols with 2-(p-bromobenzoyl)benzoic acid (Ia) and 2-(p-bromobenzoyl)tetrachlorobenzoic acid (Ib).These dyes, being unsymmetrically substituted phthalides where the cent
