Check Digit Verification of cas no

The CAS Registry Mumber 848667-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,8,6,6 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 848667-32:
(8*8)+(7*4)+(6*8)+(5*6)+(4*6)+(3*7)+(2*3)+(1*2)=223
223 % 10 = 3
So 848667-32-3 is a valid CAS Registry Number.

Reaction of 4-aryl-1-(4-oxo-3,4-dihydrothieno-[2,3-d]pyrimidin-2-yl) thiosemicarbazides with dimethyl acetylenedicarboxylate

Vas'kevich,Zborovskii,Staninets,Chernega

, p. 1047 - 1052 (2007/10/03)

4-Aryl-1-(4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thiosemicarbazides react with dimethyl acetylenedicarboxylate in methanol to give the corresponding methyl {3-aryl-4-oxo-2-[(4-oxo-3,4-dihydro-thieno[2,3-d]pyrimidin-2-yl) hydrazono]-1,3-thiazolidin-5-ylidene}acetates, whereas in dioxane methyl 5-aryl-amino-2-methoxycarbonylmethyl-3-(4-oxo-3,4-dihydrothieno[2,3-d] pyrimidin-2-yl)-2,3-dihydro-1,3,4-thiadiazole-2-carboxylates are mainly formed.
