Check Digit Verification of cas no

The CAS Registry Mumber 1263820-40-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,8,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1263820-40:
(9*1)+(8*2)+(7*6)+(6*3)+(5*8)+(4*2)+(3*0)+(2*4)+(1*0)=141
141 % 10 = 1
So 1263820-40-1 is a valid CAS Registry Number.

Regioselective FeCl3-promoted biomimetic synthesis of dimeric isorhapontigenin

Li, Wenling,Luo, Yaling,Li, Hongfu,Zang, Peng,Han, Xiaoqian

experimental part, p. 3822 - 3826 (2011/01/12)

An efficient approach to the preparation of natural (±)-gneafricanin F and the first synthesis of (±)-gnemonol M were developed. The regioselective, oxidative coupling of 5-tert-butylisorhapontigenin catalyzed by FeCl36H2O in different solvent systems was used as the key synthetic step.
