Check Digit Verification of cas no

The CAS Registry Mumber 92521-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,5,2 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92521-65:
(7*9)+(6*2)+(5*5)+(4*2)+(3*1)+(2*6)+(1*5)=128
128 % 10 = 8
So 92521-65-8 is a valid CAS Registry Number.

Hydrogen-deuterium exchange and rearrangement of polycyclic aromatic hydrocarbons in dilute acid medium at elevated temperatures

Werstiuk, Nick Henry,Timmins, George

, p. 3218 - 3220 (2007/10/02)

The high temperature-dilute acid (HTDA) method has been applied to the preparation of perdeuterated polycyclic aromatic hydrocarbons.Naphthalene (1), 1-methylnaphthalene(2), 2-methylnaphthalene (3), anthracene (4), phenanthrene (5), chrysene (6), pyrene (7), benzanthracene (8), benzopyrene (9), 1,1'-binaphthyl (10), 1,2'-binaphthyl (11), and 2,2'-binaphthyl (12) have been perdeuterated in high yield in dilute DCl-D2O solutions at elevated temperatures (240-280 deg C). 2, 3, 10, 11, and 12 also rearrange.
