Check Digit Verification of cas no

The CAS Registry Mumber 1283234-25-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,2,3 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1283234-25:
(9*1)+(8*2)+(7*8)+(6*3)+(5*2)+(4*3)+(3*4)+(2*2)+(1*5)=142
142 % 10 = 2
So 1283234-25-2 is a valid CAS Registry Number.

Copper-catalyzed C-P bond construction via direct coupling of phenylboronic acids with H-phosphonate diesters

Zhuang, Rongqiang,Xu, Jian,Cai, Zhenshi,Tang, Guo,Fang, Meijuan,Zhao, Yufen

, p. 2110 - 2113 (2011)

A mild and efficient method was developed for the copper-catalyzed additions of H-phosphonate diesters to boronic acids under the copper catalyst system Cu2O/1,10-phenanthroline. To the best of our knowledge this finding is the first example of a copper-catalyzed synthesis of aryl phosphonates from arylboronic acids and H-phosphonate dialkyl esters.
