1257322-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1257322-94-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,2 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1257322-94:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*2)+(3*2)+(2*9)+(1*4)=153
153 % 10 = 3
So 1257322-94-3 is a valid CAS Registry Number.

Synthesis of (E)-diethyl 6,6′-(diazene-1,2-diyl)bis(5-cyano-2-methyl- 4-phenylnicotinates), a new type of 2,2′-azopyridine dyes

supporting information; experimental part, p. 6278 - 6281 (2011/01/04)

An unexpected, but simple method for the efficient synthesis of new 2.2′-azopyridine dyes, such as (E)-diethyl 6,6′-(diazene-1,2-diyl) bis(5-cyano-2-methyl-4-phenylnicotinates) (2, 4, 6, 8, 10, and 12), based on the treatment of ethyl 6-amino-5-cyano-2-methyl-4-arylnicotinates (1, 3, 5, 7, 9, and 11) with NBS/benzoyl peroxide, is described. The X-ray diffraction analysis and the UV-vis absorption spectra of dye 2 are reported and discussed.
