1208459-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1208459-70-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,8,4,5 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1208459-70:
(9*1)+(8*2)+(7*0)+(6*8)+(5*4)+(4*5)+(3*9)+(2*7)+(1*0)=154
154 % 10 = 4
So 1208459-70-4 is a valid CAS Registry Number.

Syntheses of extreme sterically hindered 4-methoxyboronic acids
Diemer, Vincent,Chaumeil, Hélène,Defoin, Albert,Carré, Christiane
experimental part, p. 918 - 929 (2010/03/25)
4-Iodoanisoles 3a,b, 3d and 4-bromoanisoles 4a-d were readily obtained. An extreme steric hindrance precluded obtaining 3c. Catalytic borylation of 3a,b, 3d followed by hydrolysis of boronic ester 26a,b, 26d easily provided the boronic acids 5a,b, 5d. Com
