Check Digit Verification of cas no

The CAS Registry Mumber 1138-67-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1138-67:
(6*1)+(5*1)+(4*3)+(3*8)+(2*6)+(1*7)=66
66 % 10 = 6
So 1138-67-6 is a valid CAS Registry Number.

Biotransformation of diphenyl ether by the yeast Trichosporon beigelii SBUG 752

Schauer, Frieder,Henning, Kirsten,Pscheidl, Helmut,Wittich, Rolf M.,Fortnagel, Peter,et al.

, p. 173 - 180 (2007/10/03)

Trichosporon beigelii SBUG 752 was able to transform diphenyl ether. By TLC, HPLC, GC, GC-MS, NMR- and UV-spectroscopy, several oxidation products were identified. The primary attack was initiated by a monooxygenation step, resulting in the formation of 4-hydroxydiphenyl ether, 2-hydroxydiphenyl ether and 3-hydroxydiphenyl ether (48:47:5). Further oxidation led to 3,4-dihydroxydiphenyl ether. As a characteristic product resulting from the cleavage of an aromatic ring, the lactone of 2-hydroxy-4-phenoxymuconic acid was identified. The possible mechanism of ring cleavage to yield this metabolite is discussed.
