Check Digit Verification of cas no
The CAS Registry Mumber 14233-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,3 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14233-37:
(7*1)+(6*4)+(5*2)+(4*3)+(3*3)+(2*3)+(1*7)=75
75 % 10 = 5
So 14233-37-5 is a valid CAS Registry Number.

Concerning the Question of Covalent Bonding in Hypericin-Chromoproteins: Schiff Base Formation?
Falk, H.,Mueller, N.,Oberreiter, M.
, p. 313 - 324 (1994)
Depending on the reaction conditions, peri-hydroxy substituted anthraquinones like 1,8-dihydroxyanthraquinone and 1,4-dihydroxyanthraquinone could be derivatized with ammonia, propylamine, isopropylamine, and a lysine derivative to yield a variety of imino and amino substitution and addition products.However, hypericin resisted such derivatization under a variety of reaction conditions.Therefore, the hypothesis that hypericin is bound to its apoprotein in photopigments via a Schiff base to the ε-amino group of a lysine residue or a terminal amino group seems to be rather unlikely. - Keywords.Hypericin; Stentor; Schiff base; Anthraquinone imines; Aminoanthraquinones.
