Check Digit Verification of cas no

The CAS Registry Mumber 130548-10-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,5,4 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130548-10:
(8*1)+(7*3)+(6*0)+(5*5)+(4*4)+(3*8)+(2*1)+(1*0)=96
96 % 10 = 6
So 130548-10-6 is a valid CAS Registry Number.

ABSOLUTE CONFIGURATION OF THE RUBIGINONES AND PHOTO-INDUCED OXIDATION OF THE C1 HYDROXYL OF THE ANTIBIOTICS TO A KETONE

Oka, Masahisa,Konishi, Masataka,Oki, Toshikazu,Ohashi, Mamoru

, p. 7473 - 7474 (1990)

The absolute stereochemistry of rubiginones A1, A2, B1, B2, C1 and C2 has been established by NMR spectral analysis using the O-methylmandelate method.A facile photoinduced oxidation of rubiginones A1, B1 and C1 to rubigignones A2, B2 and C2, respectively, is discussed in relation to the absolute stereochemistry.

A facile synthesis of the angucyclinone antibiotic (+)-rubiginone B 2 involving the BF3-mediated Diels-Alder reaction of juglone

Motoyoshiya, Jiro,Masue, Yusuke,Iwayama, Gento,Yoshioka, Sachiko,Nishii, Yoshinori,Aoyama, Hiromu

, p. 2099 - 2102 (2004)

A short synthesis of (+)-rubiginone B2 is reported. The BF 3-mediated Diels-Alder reaction of juglone and (R)-3-methyl-1- vinylcyclohexene followed by aromatization gave the anthraquinone as the desired regioisomer, which was converted into the target antibiotic after a two-step operation.
