Check Digit Verification of cas no

The CAS Registry Mumber 1389313-09-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,9,3,1 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1389313-09:
(9*1)+(8*3)+(7*8)+(6*9)+(5*3)+(4*1)+(3*3)+(2*0)+(1*9)=180
180 % 10 = 0
So 1389313-09-0 is a valid CAS Registry Number.

Synthesis of novel isoxazolyl bis-thiazolo[3,2-a]pyrimidines

Rajanarendar,Ramakrishna,Rama Murthy

, p. 899 - 902 (2012/09/07)

A new synthetic strategy for the synthesis of novel 3-(3-(3-methyl-4- nitroisoxazol-5-yl)-2-phenyl-1-(5,7-diaryl-7H-thiazolo[3,2-a]pyrimidin-3-yl) propyl)-5,7-diaryl-7H-thiazolo[3,2-a] pyrimidines (7a-i) analogues is described. Reaction of 3-(2-(3-methyl-4-nitroisoxazole-5-yl)-1-phenylethyl)pentane-2,4- dione (3) with two moles of thiourea in presence of iodine and CuO afforded 4-(1-(2-aminothiazol-4-yl)-3-(3-methyl-4-nitroisoxazol-5-yl)-2-aryl propyl-thiazol-2-amine (5). Compound 5 on reaction with two moles of chalcone (6) furnished novel 3-(3-(3-methyl-4-nitroisoxazol-5-yl)-2-phenyl-1-(5,7-diaryl- 7H-thiazolo[3,2-a]pyrimidin-3-yl)propyl)-5,7-diaryl-7H-thiazolo[3,2-a] pyrimidines (7a-i).
