Check Digit Verification of cas no

The CAS Registry Mumber 557784-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,7,8 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 557784-95:
(8*5)+(7*5)+(6*7)+(5*7)+(4*8)+(3*4)+(2*9)+(1*5)=219
219 % 10 = 9
So 557784-95-9 is a valid CAS Registry Number.

Dipolar cycloaddition reactions with thiazolonylhydrazones: A new route for the synthesis of several new thienyl- and furyl-thiazolonylpyrrolopyrazole derivatives of expected biological activities

Gaber, Hatem M.

, p. 417 - 424 (2003)

Several new pyrrolopyrazoles were synthesized via the reactions of each of 2-thiophenecarboxaldehyde thiazolonylhydrazone or 2-furaldehyde thiazolonylhydrazone with N-substituted maleimides followed by partial dehydogenation using bromobenzene and complete aromatization using nitrobenzene. Structures were established on the basis of elemental analyses and spectroscopic data studies.
