Check Digit Verification of cas no
The CAS Registry Mumber 109086-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,8 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109086-74:
(8*1)+(7*0)+(6*9)+(5*0)+(4*8)+(3*6)+(2*7)+(1*4)=130
130 % 10 = 0
So 109086-74-0 is a valid CAS Registry Number.

CARBON TRANSFER REACTIONS WITH HETEROCYCLES-V. A FACILE SYNTHESIS OF NIFEDIPINE AND ANALOGUES
Singh, Harjit,Singh, Kamaljit
, p. 3967 - 3974 (2007/10/02)
Oxazolidines and tetrahydro-(2H)-1,3-oxazines transfer their C(2) units at the carbonyl group oxidation level to alkyl-β-amino/anilinocrotonates to form 1,4-dihydropyridines elaborated at C-4.
