123136-45-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123136-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,3 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 123136-45:
(8*1)+(7*2)+(6*3)+(5*1)+(4*3)+(3*6)+(2*4)+(1*5)=88
88 % 10 = 8
So 123136-45-8 is a valid CAS Registry Number.

A new In-SiO2 composite catalyst in the solvent-free multicomponent synthesis of Ca2+ channel blockers nifedipine and nemadipine B

Affeldt, Ricardo F.,Benvenutti, Edilson V.,Russowsky, Dennis

experimental part, p. 1502 - 1511 (2012/07/30)

An In-SiO2 composite was prepared by the sol-gel method and was applied as a heterogeneous Lewis acid catalyst in the multicomponent Hantzsch synthesis of symmetrical and non-symmetrical 1,4-DHPs. The Ca2+ channel blockers nifedipine and nemadipine B were synthesized in a single step through a solvent-free protocol.
