334668-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 334668-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,6,6 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 334668-94:
(8*3)+(7*3)+(6*4)+(5*6)+(4*6)+(3*8)+(2*9)+(1*4)=169
169 % 10 = 9
So 334668-94-9 is a valid CAS Registry Number.

Ring closure reactions of pyrido[2,3-d]pyrimidines to pyrano[2′, 3′:4,5]- and oxazolo[5′,4′:4,5]pyrido[2,3-d]pyrimidines

Tinh, Dang Van,Stadlbauer, Wolfgang

experimental part, p. 1359 - 1364 (2009/04/07)

(Chemical Equation Presented) The cyclocondensation of 5-hydroxy-pyrido[2, 3-d]pyrimidines 1 with malonates gives pyrano[2′,3′:4,5]-pyrido[2,3- d]pyrimidines 2. Nitration of 1 and reduction with zinc in the presence of carboxylic acids/anhydrides gave 2-a
