60460-71-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60460-71-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,4,6 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 60460-71:
(7*6)+(6*0)+(5*4)+(4*6)+(3*0)+(2*7)+(1*1)=101
101 % 10 = 1
So 60460-71-1 is a valid CAS Registry Number.

The modified-Mannich reaction: Conversion of arylboronic acids and subsequent coupling with paraformaldehyde and amines toward the one-pot synthesis of Mannich bases and benzoxazines

Liu, Juan,Yuan, Gaoqing

supporting information, p. 1470 - 1473 (2017/03/23)

A modified Mannich reaction has been developed for the synthesis of Mannich bases and benzoxazines via the oxidative hydroxylation of arylboronic acids and subsequent coupling with paraformaldehyde and amines in one pot. This modified Mannich reaction is easily carried out to afford the target products in good to excellent yields and tolerates a variety of functional groups.

Regioselective mannich reaction of phenols under high pressure using dichloromethane as C1 unit

Matsumoto, Kiyoshi,Joho, Kouta,Mimori, Seisuke,Iida, Hirokazu,Hamana, Hiroshi,Kakehi, Akikazu

scheme or table, p. 1061 - 1067 (2009/06/28)

Regioselectivity in Mannich reaction of 4-, 3-, and 2-substituted phenols with typical heterocyclic amines are investigated under reaction conditions developed by us. Phenol and 4-alkyl, and 4-chlorophenols in the title reaction predominantly gave the corresponding 2-(aminomethyl)phenols, while 4-methoxyphenol afforded, in addition to the mono(aminomethyl)phenols, a considerable amount of the bis adducts. Peculiarly enough, 3-methylphenol with amines afforded 3-methyl-4-(aminomethyl)phenols whereas 2-methylphenol produced 2-methyl-6-(aminomethyl)phenols.
