107640-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107640-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,4 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107640-23:
(8*1)+(7*0)+(6*7)+(5*6)+(4*4)+(3*0)+(2*2)+(1*3)=103
103 % 10 = 3
So 107640-23-3 is a valid CAS Registry Number.

Thieno Compounds. Part 5: Basically Substituted Thienopyrimidines

Boehm, R.,Pech, R.,Haubold, Gudrun,Hannig, E.

, p. 23 - 25 (2007/10/02)

Derivatives of Thienopyrimidine are the analogous structures of quinazolines, which are used in therapy, especially against hypertonia.Some new basically substituted thienopyrimidines were synthesized from 3,4-dihydro-4-oxothienopyrimidines with 4-chlorothienopyrimidines as intermediates.The corresponding 2,4-dibasic derivatives were received in the same way by transformation of the 1,2,3,4-tetrahydro-2,4-dioxothienopyrimidines.Derivatives with two different basic groups were obtained by a step-wise substitution of the both chlorine-atoms.I the case of a reaction with an aliphatic amine to substitute the chlorine in position 4 followed by a reaction with an aromatic amine both the chlorine in position 2 and the basic group in position 4 are replaced.
