Check Digit Verification of cas no

The CAS Registry Mumber 77542-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,4 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77542-75:
(7*7)+(6*7)+(5*5)+(4*4)+(3*2)+(2*7)+(1*5)=157
157 % 10 = 7
So 77542-75-7 is a valid CAS Registry Number.

Naphthoquinone Mono- and Di-methide Lactones

Carey, John L.,Shand, Charles A.,Thomson, Ronald H.,Greenhalgh, Colin W.

, p. 1957 - 1962 (2007/10/02)

Monolactones which are derivatives of 7-hydroxynaphthopyran-2,6-dione are obtained by reaction of simple juglones with ethyl chloroformylacetate, and by condensation of mandelic acid with 2,6-dibromo-1,5-dihydroxynaphthalene.Dilactones are formed
