Check Digit Verification of cas no

The CAS Registry Mumber 1431793-58-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,7,9 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1431793-58:
(9*1)+(8*4)+(7*3)+(6*1)+(5*7)+(4*9)+(3*3)+(2*5)+(1*8)=166
166 % 10 = 6
So 1431793-58-6 is a valid CAS Registry Number.

Efficient synthesis of oxygenated terphenyls and other oligomers: Sequential arylation reactions through phenol oxidation-rearomatization

Dohi, Toshifumi,Kamitanaka, Tohru,Watanabe, Shohei,Hu, Yinjun,Washimi, Naohiko,Kita, Yasuyuki

supporting information, p. 13614 - 13618 (2013/01/15)

One by one: Starting from simple phenols, a diverse series of oxygenated terphenyl compounds can be prepared in a concise and practical manner using sequential arylation reactions involving phenol oxidation/rearomatization and quinone monoacetal intermediates (see scheme). Many of the terphenyl products can be used for preparing well-defined oligomers and, furthermore, contain valuable functional groups that can be transformed for further diversification. Copyright
