Check Digit Verification of cas no

The CAS Registry Mumber 20925-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,2 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20925-82:
(7*2)+(6*0)+(5*9)+(4*2)+(3*5)+(2*8)+(1*2)=100
100 % 10 = 0
So 20925-82-0 is a valid CAS Registry Number.

RE-EXPLORATION OF THE THERMOLYSIS OF ARYLAZIDES AS A ROUTE TO 3H-AZEPINES: CHEMISTRY OF AZIDOACETOPHENONES

Ohba, Yoshihiro,Kubo, Shinji,Nishiwaki, Tarozaemon,Aratani, Noritoshi

, p. 457 - 460 (2007/10/02)

Thermolysis of 3-azidoacetophenone in methanol in a sealed glass ampoule gave 6-acetyl- and 4-acetyl-3H-azepines in moderate yields, whose kinetic data a=132.6+/-1.7 kJmol-1, ΔS443= -12.1=/-4.2 JK-1mol-1> were obtained by means of HPLC.Photolysis of this azide in methanol gave the same pair of the 3H-azepines in poor yields.Thermolysis of 4-azidoacetphenone under the similar conditions afforded a moderate yield of 5-acetyl-3H-azepine.For comparison, photolyses of 4- and 2-azidoacetophenones were also studied.
