4-Ethoxycarbonyl-2-nitrophenylboronic acid
Check Digit Verification of cas no
The CAS Registry Mumber 5785-70-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5785-70:
(6*5)+(5*7)+(4*8)+(3*5)+(2*7)+(1*0)=126
126 % 10 = 6
So 5785-70-6 is a valid CAS Registry Number.

A facile and convenient synthesis of functionalized ortho- nitrophenylboronic acids
Collibee, Scott E.,Yu, Jiaxin
, p. 4453 - 4455 (2007/10/03)
A variety of ortho-nitrophenylboronic acids bearing functional groups such as cyano, nitro, halo, α-bromomethyl, and ester were prepared in good yields via I-Mg exchange followed by quenching with trimethyl borate. All reagents employed in this procedure are commercially available and were used without further purification, and the procedure can be executed in about an hour.
