121567-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121567-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,6 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121567-85:
(8*1)+(7*2)+(6*1)+(5*5)+(4*6)+(3*7)+(2*8)+(1*5)=119
119 % 10 = 9
So 121567-85-9 is a valid CAS Registry Number.

SYNTHESIS AND TAUTOMERISM OF 5,7-DIARYL-4,7(6,7)-DIHYDROTETRAZOLOPYRIMIDINES
Orlov, V. D.,Desenko, S. M.,Pivnenko, N. S.
, p. 1233 - 1237 (2007/10/02)
5,7-Diaryl-4,7(6,7)-dihydrotetrazolopyrimidines were synthesized by the cyclocondensation of 5-aminotetrazole with chalcones.The tautomerism of the compounds obtained is discussed.
