646522-36-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 646522-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,6,5,2 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 646522-36:
(8*6)+(7*4)+(6*6)+(5*5)+(4*2)+(3*2)+(2*3)+(1*6)=163
163 % 10 = 3
So 646522-36-3 is a valid CAS Registry Number.

A concise synthesis of pyrimidinophanes from 6-aryl-5-cyano-2-thiouracil

Upadhyay,Agarwal, Nidhi,Goel, Atul,Ram, Vishnu Ji.

, p. 380 - 382 (2007/10/03)

A convenient synthesis of 2,3- and 2,4-pyrimidinophanes (3,5,6) has been described from 6-aryl-5-cyano-2-thiouracils (1a-c). A reaction of 2-thiouracil with dibromomethane produced 2a-c, which on further interaction with dihaloalkane under basic condition produced 2,3-pyrimidinophanes (3a,b). Halogenation of 2a,c with POCl3 led to yield respective chloropyrimidines (4a,b), which on further reaction with diaminoalkane and 1,4-phenylenediamine separately yielded 2,4-pyrimidinophanes (5a-d and 6a,b).
