Check Digit Verification of cas no

The CAS Registry Mumber 103522-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,5,2 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103522-59:
(8*1)+(7*0)+(6*3)+(5*5)+(4*2)+(3*2)+(2*5)+(1*9)=84
84 % 10 = 4
So 103522-59-4 is a valid CAS Registry Number.

The Photo-oxidation of meso-Tetraphenylporphyrins

Cavaleiro, Jose A. S.,Neves, Maria G. P. S.,Hewlins, Michael J. E.,Jackson, Anthony H.

, p. 1937 - 1943 (2007/10/02)

The photo-oxidation of meso-tetraphenylporphyrin (TPP) dianion in methanol affords a purple benzoyl bilinone (5b) by addition of singlet oxygen, followed by ring-opening and addition of methanol; similar products (5a) and (5c) can be formed by addition of

Structures of the Ring-opened Oxidation Products from meso-Tetraphenylporphyrin

Cavaleiro, Jose A. S.,Hewlins, Michael J. E.,Jackson, Anthony H.,Neves, G. P. Maria S.

, p. 142 - 144 (2007/10/02)

The products formed by chemical, or photochemical, oxidation of meso-tetraphenylporphyrin, or its metal complexes, are now shown to have the novel violinoid structure (3) (rather than a biliverdinoid structure) as shown by spectroscopic and (13)C-labelling studies.
