Check Digit Verification of cas no

The CAS Registry Mumber 1226896-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,8,9 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1226896-32:
(9*1)+(8*2)+(7*2)+(6*6)+(5*8)+(4*9)+(3*6)+(2*3)+(1*2)=177
177 % 10 = 7
So 1226896-32-7 is a valid CAS Registry Number.

Synthesis of Polycyclic Cyclohexadienone through Alkoxy-Oxylactonization and Dearomatization of 3′-Hydroxy-[1,1′-biphenyl]-2-carboxylic Acids Promoted by Hypervalent Iodine

Deng, Qingfu,Hu, Wen,Hussain, Muhammad Ijaz,Xia, Wen,Xiong, Yan,Zhang, Xiaohui

, p. 3125 - 3133 (2020)

Alkox-oxylactonization and dearomatization of 3′-hydroxy-[1,1′-biphenyl]-2-carboxylic acid simultaneously promoted by hypervalent iodine have been developed using stoichiometric PhI(OAc)2 or a catalytic amount of chiral aryl-λ3-iodane generated in situ. This reaction provides a concise method to synthesize diverse polycyclic cyclohexadienones as potential inhibitors of DNA polymerase under mild reaction conditions.
