Check Digit Verification of cas no

The CAS Registry Mumber 146864-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 146864-75:
(8*1)+(7*4)+(6*6)+(5*8)+(4*6)+(3*4)+(2*7)+(1*5)=167
167 % 10 = 7
So 146864-75-7 is a valid CAS Registry Number.

First Total Syntheses of Tetracenomycins C and X

Sato, Shogo,Sakata, Keiichiro,Hashimoto, Yoshimitsu,Takikawa, Hiroshi,Suzuki, Keisuke

, p. 12608 - 12613 (2017)

The first total syntheses of tetracenomycins C and X were achieved, featuring 1) preparation of a hexasubstituted naphthonitrile oxide by successive benzyne cycloadditions and an oxidative ring-opening reaction; 2) a novel ortho-quinone mono-acetal as the A-ring unit; 3) construction of three contiguous stereogenic centers by an asymmetric benzoin cyclization, an isoxazole oxidation, and a stereoselective reduction.
