Check Digit Verification of cas no

The CAS Registry Mumber 1629050-67-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,9,0,5 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1629050-67:
(9*1)+(8*6)+(7*2)+(6*9)+(5*0)+(4*5)+(3*0)+(2*6)+(1*7)=164
164 % 10 = 4
So 1629050-67-4 is a valid CAS Registry Number.

Repetitive two-step method for o,o,p- and o,p-oligophenylene synthesis through Pd-catalyzed cross-coupling of hydroxyterphenylboronic acid

Yamaguchi, Miyuki,Kimura, Takeshi,Shinohara, Naomi,Manabe, Kei

, p. 15207 - 15219 (2014/01/17)

A repetitive two-step method involving the Pd-catalyzed Suzuki-Miyaura coupling of hydroxyterphenylboronic acid and the subsequent nonaflation of the hydroxy group has been developed for the synthesis of oligophenylenes. This method readily afforded o,o,p- and o,p-oligophenylenes with defined chain lengths. X-ray crystallography was employed to obtain the structure of the o,p-oligophenylene 9-mer.
