219786-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219786-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,8 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 219786-83:
(8*2)+(7*1)+(6*9)+(5*7)+(4*8)+(3*6)+(2*8)+(1*3)=181
181 % 10 = 1
So 219786-83-1 is a valid CAS Registry Number.

Synthesis of 3-5-diacyl-4-phenyl-1,4-dihydropyridines
Bennasar, M.-Lluisa,Juan, Cecilia,Bosch, Joan
, p. 9275 - 9278 (2007/10/03)
3,5-Diacyl-4-phenyl-1,4-dihydropyridines have been synthesized via a regio- and chemoselective addition of Ph2Cu(CN)Li2 to β-substituted N- alkylpyridinium salts, followed by acylation of the intermediate 1,4- dihydropyridines with t
