Check Digit Verification of cas no

The CAS Registry Mumber 38696-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,6,9 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 38696-56:
(7*3)+(6*8)+(5*6)+(4*9)+(3*6)+(2*5)+(1*6)=169
169 % 10 = 9
So 38696-56-9 is a valid CAS Registry Number.

PHOTOCHEMICAL AND THERMAL INTERCONVERSIONS OF THREE DIMERS OF 2,4,5-TRIPHENYLIMIDAZOLYL (LOPHYL)

Goto, Toshio,Tanino, Hideo,Kondo, Tadao

, p. 431 - 434 (2007/10/02)

The photochromic lophyl dimers, A and B, are interconverted by uv irradiation, while these two dimers and thermochromic dimer C can be equilibrated in benzene at 100 deg C.Compositions at equilibrium using the corresponding three dimers of 2-(p-tolyl)-4,5-diphenylimidazolyl are A:B = 96:4 and A:B:C = 14:18:68, respectively.
