121629-21-8 Usage
Uses
4''-Hydroxybiphenyl-3-carboxylic Acid is a biaryl compound that can be prepared via palladium bis[(dipiperidinylphosphino)amino]phenyl-catalyzed Suzuki-Miyaura cross coupling reactions of organoboronic acids or trifluoroborates and aryl bromides and can also be synthesized by simultaneous hydroxylation and carboxylation of biphenyls. 4''-Hydroxybiphenyl-3-carboxylic Acid is a useful building block with applications in various syntheses.
Check Digit Verification of cas no
The CAS Registry Mumber 121629-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,2 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121629-21:
(8*1)+(7*2)+(6*1)+(5*6)+(4*2)+(3*9)+(2*2)+(1*1)=98
98 % 10 = 8
So 121629-21-8 is a valid CAS Registry Number.
