Check Digit Verification of cas no

The CAS Registry Mumber 84661-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,6 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84661-32:
(7*8)+(6*4)+(5*6)+(4*6)+(3*1)+(2*3)+(1*2)=145
145 % 10 = 5
So 84661-32-5 is a valid CAS Registry Number.

Synthesis of some substituted isoxazolo [5,4-d] pyrimidine-4(5H)-ones and their biological evaluation

Godhani,Kaila,Sanghani,Dobariya

, p. 225 - 228 (2013/09/24)

Substituted anilines vk'ere condensed Wiih ethyl cyanoacetate in xylene to get corresponding 2-cyano-N-phenylacetamides 1a-1h, which upon reaction with sodium bicarbonate and acetic anhydride gave corresponding compounds 2-cyano-3-hydroxy-N-phenylbut-2-enamides 2a-2h, which further upon reaction with hydroxyl amine hydrochloride in methanol yielded corresponding 5-amino-3-methyl-N-phenylisoxazole-4-carboxamides 3a-3h. 3a-3h when treated with acetic anhydride and triethyl orthoformate, gave substituted isoxazolo [5,4-d] pyrimidin-4 (5H)-ones 4a-4h.
