21470-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21470-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,7 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21470-20:
(7*2)+(6*1)+(5*4)+(4*7)+(3*0)+(2*2)+(1*0)=72
72 % 10 = 2
So 21470-20-2 is a valid CAS Registry Number.

A really convenient synthesis of 2',3''''-dimethyl-p-sexiphenyl
Kauffman, Joel M.
, p. 918 - 920 (2007/10/03)
Modern cross-couplings of arylmagnesium bromides with dibromoarenes gave 3,3''''-dimethylquaterphenyl and, from its dibromination product, 2',3''''- dimethyl-p-sexiphenyl (DMSP) in high yield with use of the air-stable PdCl2·dppb in catalytic a
