Check Digit Verification of cas no

The CAS Registry Mumber 339190-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,1,9 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 339190-10:
(8*3)+(7*3)+(6*9)+(5*1)+(4*9)+(3*0)+(2*1)+(1*0)=142
142 % 10 = 2
So 339190-10-2 is a valid CAS Registry Number.

Synthesis of a regio-isomer of kealiiquinone, a marine benzimidazole alkaloid

Nakamura, Seikou,Tsuno, Naoki,Yamashita, Masayuki,Kawasaki, Ikuo,Ohta, Shunsaku,Ohishi, Yoshitaka

, p. 429 - 436 (2001)

Treatment of 1,3-dialkyl-2-(phenylthio)benzimidazolium salts 3 and 1,3-dialkyl-2-phenylthio-1H-imidazolium salts 7 with aq. K2CO3 gives 1,3-dialky1-1,3-dihydrobenzimidazol-2-ones 4 and 1,3-dialkyl-1,3-dihydroimidazol-2-ones 8, respectively, in 22-94% yield. A regio-isomer 17 of kealiiquinone, a marine benzimidazole alkaloid, where the 4-methoxyphenyl group at the 4-position migrates to the 9-position, is synthesized by application of the reaction. Cytotoxity of 17 and kealiiquinone against 39 human cancer cells is evaluated. They have weak activity but a unique mechanism of action.
