Check Digit Verification of cas no

The CAS Registry Mumber 1156464-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,6,4,6 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1156464-18:
(9*1)+(8*1)+(7*5)+(6*6)+(5*4)+(4*6)+(3*4)+(2*1)+(1*8)=154
154 % 10 = 4
So 1156464-18-4 is a valid CAS Registry Number.

Electrophilic heterocyclization of 6-alken(yn)ylsulfanyl-pyrazolo[3,4-d] pyrimidin-4(5H)-ones

Bentya,Vas'kevich,Bol'but,Vovk,Staninets,Turov,Rusanov

, p. 1362 - 1368 (2008)

6-Allylsulfanyl-1-arylpyrazolo[3,4-d]pyrimidin-4(5H)-ones react with iodine and sulfuric acid to give angular pyrazolothiazolopyrimidine derivatives. The reaction of 6-(prop-2-yn-1-ylsulfanyl)-1-(4-tolyl)-pyrazolo[3,4-d]pyrimidin- 4(5H)-one with sulfuric acid gives angularly fused pyrazolo[4,3-e][1,3]thiazolo- [3,2-a]pyrimidin-4-one, whereas in the reaction with sodium methoxide linearly fused pyrazolo[3,4-d][1,3]-thiazolo[3,2-a]pyrimidin-4-one was formed. Linearly fused pyrazolo[3′,4′:4,5]pyrimido[2,1-b][1,3]thiazole derivatives were also obtained by reaction of 1-aryl-6-(3-phenylprop-2-en-1-ylsulfanyl) pyrazolo[3,4-d]pyrimidin-4(5H)-ones with sulfuric acid.
