Check Digit Verification of cas no
The CAS Registry Mumber 476-37-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 476-37:
(5*4)+(4*7)+(3*6)+(2*3)+(1*7)=79
79 % 10 = 9
So 476-37-9 is a valid CAS Registry Number.

Simple preparative synthesis of spinochrome E, a pigment from sea urchins of the genus Echinothrix
Borisova,Anufriev
, p. 202 - 204 (2012)
A preparative synthesis of spinochrome E (2,3,5,6,7,8-hexahydroxy-1,4- naphthoquinone, 1), a metabolite of sea urchins of the genus Echinothrix, is proposed starting from 2,3-dichloro-6,7-diethoxynaphthazarine (4) with simultaneous substitution of the Cl atoms by hydroxyl- and nitro-groups, reduction of the latter, and subsequent removal of alkoxy groups and hydrolysis of the amine in the resulting 3-amino-2-hydroxy-6,7-diethoxynaphthazarine (6).
