Check Digit Verification of cas no

The CAS Registry Mumber 114170-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,1,7 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 114170-91:
(8*1)+(7*1)+(6*4)+(5*1)+(4*7)+(3*0)+(2*9)+(1*1)=91
91 % 10 = 1
So 114170-91-1 is a valid CAS Registry Number.

Studies on the Pyridylpyrazolone System: Part V - Cyclocondensation of 1-Phenyl-3-(3'-pyridyl)-2-pyrazolin-5-one with Ethyl Acetoacetate and Related Compounds

Abdel-Megeed, Mohamed F.

, p. 827 - 831 (2007/10/02)

The reaction of 1-phenyl-3-(3'-pyridyl)-2-pyrazolin-5-one (I) with ethyl acetoacetate, diethyl acetonedicarboxylate and diethyl β,β-dioxobenzene-1,4-dipropionate yields the corresponding 1H-pyranopyrazolones (II-IV).Compound II is readily converted
