93617-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93617-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,1 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93617-79:
(7*9)+(6*3)+(5*6)+(4*1)+(3*7)+(2*7)+(1*9)=159
159 % 10 = 9
So 93617-79-9 is a valid CAS Registry Number.

REGIOSELECTIVE ADDITION OF TITANIUM ENOLATES TO 1-ACYLPYRIDINIUM SALTS. A CONVENIENT SYNTHESIS OF 4-(2-OXOALKYL)PYRIDINES
Comins, Daniel L.,Brown, Jack D.
, p. 3297 - 3300 (2007/10/02)
Titanium enolates add to the 4-position of 1-phenoxycarbonylpyridinium salts to give 1,4-dihydropyridines; subsequent aromatization provides 4-(2-oxoalkyl)pyridines.
