Check Digit Verification of cas no
The CAS Registry Mumber 869806-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,8,0 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 869806-73:
(8*8)+(7*6)+(6*9)+(5*8)+(4*0)+(3*6)+(2*7)+(1*3)=235
235 % 10 = 5
So 869806-73-5 is a valid CAS Registry Number.

Synthesis and oxidation of 'non-annulated' vitamin E-like compounds
Rosenau, Thomas,Stanger, Amnon
, p. 7845 - 7848 (2005)
Two model compounds (3 and 4) having the typical α-tocopherol-type substitution pattern of the aromatic ring, but lacking the annulated pyran ring, have been synthesized. Upon oxidation, the two possible ortho-quinone methides (oQMs) of each are formed in
