Check Digit Verification of cas no

The CAS Registry Mumber 147149-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,4 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 147149-89:
(8*1)+(7*4)+(6*7)+(5*1)+(4*4)+(3*9)+(2*8)+(1*9)=151
151 % 10 = 1
So 147149-89-1 is a valid CAS Registry Number.

A large scale process for the preparation of thymitaq

Malmgren, Hakan,Baeckstroem, Birthe,Solver, Ellen,Wennerberg, Johan

, p. 1195 - 1200 (2008)

The large scale manufacturing of the anticancer agent 2-amino6-methyl-5- (pyridin-4-ylsulfanyl)-3H-quinazolin-4-one dihydrochloride (thymitaq) from 6-bromo-5-methylanthranilic acid is described. The chemical route consists of two chemical steps: formation of a bromoquinazolinone and a copper-mediated Ullman-like coupling between 4-mercaptopyridine and the bromoquinazolinone. During process development, sodium hydride was replaced with sodium hydroxide and a method for removal of copper, based on 2,4,6-trimercapto-s-triazine, was developed. A number of purification operations were performed to ensure a product of pharmaceutical quality.

New straightforward synthesis of 2-amino-6-methyl-5-(pyridin-4-ylsulfanyl)- 3H-quinazolin-4-one

Chen, Wei-Min,Wan, Shan-He

, p. 53 - 61 (2007/10/03)

The synthesis of 2-amino-6-methyl-5-(pyridin-4-ylsulfanyl)-3H-quinazolin-4- one (1) was studied via three different synthetic routes starting from 4-bromo-5-methylisatin. The best route was established, which is a straightforward route via 2-guanidino-5-b
