Check Digit Verification of cas no

The CAS Registry Mumber 304012-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,0,1 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 304012-22:
(8*3)+(7*0)+(6*4)+(5*0)+(4*1)+(3*2)+(2*2)+(1*2)=64
64 % 10 = 4
So 304012-22-4 is a valid CAS Registry Number.

Synthesis of triazoles and tetrazoles condensed with spiro(benzo[h]quinazoline-5,1′-cyclohexane)

Markosyan,Kuroyan,Dilanyan

, p. 334 - 338 (2000)

Condensation of 3-R-4-oco-2-thioxo-1,2,3,4,5,6-hexahydrospiro (benzo[h]quinazoline-5,1′-cyclohexanes) with 2-ethanolamine, 3-propanolamine, and hydrazine hydrate gives the corresponding 2-ethanolamino, 2-propanolamino, and 2-hydrazino derivatives. Triazoles and tetrazoles, a- or b-condensed with benzo[h]quinazolines were obtained from 2-hydrazinobenzo[h]quinazolines depending on the presence of a substituent at position 3.
