Check Digit Verification of cas no

The CAS Registry Mumber 540535-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,5,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 540535-89:
(8*5)+(7*4)+(6*0)+(5*5)+(4*3)+(3*5)+(2*8)+(1*9)=145
145 % 10 = 5
So 540535-89-5 is a valid CAS Registry Number.

Synthesis and properties of substituted 2-methylene-hydrazono-2,3-dihydro- 3-benzo[b]furanones

Pulina,Zalesov

, p. 685 - 689 (2007)

The reaction of 2,3-dihydro-2,3-benzo[b]furandione with the triphenylphosphazines of diazo compounds leads to substituted 2-methylenehydrazono-2,3-dihydro-3-benzo[b]furanones, which are hydrolyzed in an acidic medium to the substituted methylenehydrazides
