Check Digit Verification of cas no

The CAS Registry Mumber 299464-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,4,6 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 299464-88:
(8*2)+(7*9)+(6*9)+(5*4)+(4*6)+(3*4)+(2*8)+(1*8)=213
213 % 10 = 3
So 299464-88-3 is a valid CAS Registry Number.

Synthesis of pyridazothienothiazine and pyrimidothienopyridazines

Radwan,Kamal El-Dean

, p. 299 - 313 (2000)

3-amino-4,5-diphenylthieno[2,3-c]pyridazine-2-arylcarboxamide 2 underwent cyclization with triethyl orthoformate and with nitrous acid to give the pyrimidothienopyridazines 3a-c, 4b respectively, 3-amino-4,5-diphenylthieno[2,3-c] pyridazine-2-carbohydrazide 6 reacted with aromatic aldehydes to give the corresponding carbohydrazones 7a-c. Compound 7 reacts with triethyl orthoformate, acetic anhydride or with CS2/pyridine to produce pyrimidothienopyridazines 8,9 and pyridazothienothiazine 11.
