Check Digit Verification of cas no

The CAS Registry Mumber 90685-85-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,8 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90685-85:
(7*9)+(6*0)+(5*6)+(4*8)+(3*5)+(2*8)+(1*5)=161
161 % 10 = 1
So 90685-85-1 is a valid CAS Registry Number.

A Novel Irreversible Wessely - Moser Rearrangement of a 5-Mercaptochromone

Suschitzky, John L.

, p. 275 - 276 (1984)

The first synthesis of a 5-mercaptochromone is described, which on treatment with aqueous sodium hydroxide undergoes a novel irreversible Wessely - Moser rearrangement to the corresponding 5-hydroxythiochromone.
