Check Digit Verification of cas no

The CAS Registry Mumber 79634-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,6,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79634-19:
(7*7)+(6*9)+(5*6)+(4*3)+(3*4)+(2*1)+(1*9)=168
168 % 10 = 8
So 79634-19-8 is a valid CAS Registry Number.

DYE-SENSITIZED PHOTOOXYGENATION OF TRYPTOPHAN: 3a-HYDROPEROXYPYRROLOINDOLE AS A LABILE PRECURSOR OF FORMYLKYNURENINE

Nakagava, Masako,Kato, Shiro,Kataoka, Shigehiro,Kodato, Shinichi,Watanabe, Hideyuki,et al.

, p. 1013 - 1026 (2007/10/02)

The isolation, structure determination, and reactivity of the tricyclic labile hydroperoxides 10 and 2 obtained by dye-sensitized photooxygenation of L-, D-, and DL-tryptophan and Nb-methoxycarbonyltryptophan ester are reported.The tricyclic hydroperoxide 10, under apprpopiate conditions, was easily convertible to formylkynurenine.Plausible mechanisms for these transformations are discussed.Keywords-tryptophan and its derivatives; dye-sensitized photooxygenation; formylkynurenine; hydroperoxypyrroloindoles; 3-hydroperoxyindolenines; 1,3-benzoxazines; CD spectra; rearrangement; ring-chain tautomerism; biological oxidation
