97307-86-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97307-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,3,0 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97307-86:
(7*9)+(6*7)+(5*3)+(4*0)+(3*7)+(2*8)+(1*6)=163
163 % 10 = 3
So 97307-86-3 is a valid CAS Registry Number.

Process for the purification of N-morpholinoalkyl dihydropyridines
-
, (2008/06/13)
N-Morpholinoalkyl dihydropyridines are purified by precipitating their acid addition salts in an acidic organic solvent, dissolving the precipitate in a two-phase solvent system and crystallizing the N-morpholinoalkyl dihydropyridines from the organic phase of the two-phase solvent system.
