Check Digit Verification of cas no

The CAS Registry Mumber 93710-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,1 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93710-63:
(7*9)+(6*3)+(5*7)+(4*1)+(3*0)+(2*6)+(1*3)=135
135 % 10 = 5
So 93710-63-5 is a valid CAS Registry Number.

NEODIHYDROTHEBAINE AND BRACTAZONINE, TWO DIBENZAZONINE ALKALOIDS OF PAPAVER BRACTEATUM

Theuns, Hubert G.,Lenting, Herman B. M.,Salemink, Cornelis A.,Tanaka, Hitoshi,Shibata, Masayoshi,et al.

, p. 1157 - 1166 (2007/10/02)

Two new dibenzazonine alkaloids, neodihydrothebaine and bractazonine were isolated from Papaver bracteatum.Their possible biosynthesis from thebaine is discussed.The structures of both new alkaloids are proven by synthesis.An isomeric dibenzazonine compound was also prepared. - Keywords: Papaver bracteatum; Papaveraceae; alkaloids; dibenzazonines; neodihydrothebaine; bractazonine; biosynthetic pathway; synthesis; 5,6,8,9-tetrahydro-2-methoxy-7-methyl-dibenzazonin-1,12-diol; 5,6,8,9-tetrahydro-2,10-dimethoxy-7-methyl-dibenzazonin-1-ol; 5,6,8,9-tetrahydro-2,11-dimethoxy-7-methyl-dibenz-azonin-1-ol; 5,6,8,9-tetrahydro-2,12-dimethoxy-7-methyl-dibenzazonin-1-ol.
