Check Digit Verification of cas no

The CAS Registry Mumber 685894-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,8,9 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 685894-13:
(8*6)+(7*8)+(6*5)+(5*8)+(4*9)+(3*4)+(2*1)+(1*3)=227
227 % 10 = 7
So 685894-13-7 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
