1228992-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228992-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,9,9 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1228992-74:
(9*1)+(8*2)+(7*2)+(6*8)+(5*9)+(4*9)+(3*2)+(2*7)+(1*4)=192
192 % 10 = 2
So 1228992-74-2 is a valid CAS Registry Number.

Manganese(III)-mediated direct phosphonylation of arenes
Xu, Wei,Zou, Jian-Ping,Zhang, Wei
experimental part, p. 2639 - 2643 (2010/06/16)
Manganese (III)-promoted direct phosphonylation of mono- and disubstituted arenes with dialkylphosphite afforded regioselective dialkylphosphonates in good yields. The reactions can apply to arenes bearing electron-donating groups and electron-withdrawing
