188439-67-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188439-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,4,3 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188439-67:
(8*1)+(7*8)+(6*8)+(5*4)+(4*3)+(3*9)+(2*6)+(1*7)=190
190 % 10 = 0
So 188439-67-0 is a valid CAS Registry Number.

Synthesis of 1,4-dihydropyridines by regioselective additions of benzylic zinc bromides to pyridinium salts and their aromatizations to 4-benzylpyridines

Krapcho, A. Paul,Waterhouse, David J.,Hammach, Abdelhakim,Di Domenico, Roberto,Menta, Ernesto,Oliva, Ambrogio,Spinelli, Silvano

, p. 781 - 794 (1997)

Benzylic zinc reagents add with high regioselectivity to 1-(phenoxycarbonyl) salts of methyl nicotinate to yield methyl-1-(phenoxycarbonyl)-4-benzyl-1,4-dihydronicotinates. The dihydronicotinates on heating with sulfur in decalin afford methyl 4-benzylnicotinates.
