Check Digit Verification of cas no

The CAS Registry Mumber 1246680-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,6,8 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1246680-87:
(9*1)+(8*2)+(7*4)+(6*6)+(5*6)+(4*8)+(3*0)+(2*8)+(1*7)=174
174 % 10 = 4
So 1246680-87-4 is a valid CAS Registry Number.

Isomerization of triphenylmethoxyl: The wieland free-radical rearrangement revisited a century later

DiLabio, Gino A.,Ingold,Lin, Shuqiong,Litwinienko, Grzegorz,Mozenson, Olga,Mulder, Peter,Tidwell, Thomas T.

, p. 5982 - 5985 (2010)

(Figure Presented) Old wisdom teaches a new lesson : The rate constant for the isomerization of thermally generated triphenylmethoxyl to Ph 2(PhO)C has been determined both experimentally and by DFT calculations (see scheme), and the results vindicated Wieland's 1911 observations and conclusions-in contrast to photochemically based findings.
