Check Digit Verification of cas no

The CAS Registry Mumber 1263034-22-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,0,3 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1263034-22:
(9*1)+(8*2)+(7*6)+(6*3)+(5*0)+(4*3)+(3*4)+(2*2)+(1*2)=115
115 % 10 = 5
So 1263034-22-5 is a valid CAS Registry Number.

An improved procedure for the synthesis of aryl phosphonates by palladium-catalysed cross-coupling of aryl halides and diethyl phosphite in polyethylene glycol

Wang, Ping,Lu, Jie,Zhang, Zhan-Hui

, p. 359 - 361 (2013)

A general and greener protocol for the synthesis of aryl phosphonates by the cross-coupling of aryl halides and diethyl phosphite using tetrakis(triphenylphosphine)palladiume/triethylamine/polyethylene glycol 600 [Pd(PPh3)4/ Et3N/PEG 600] as an efficient catalytic system has been developed. This procedure also avoids hazardous solvents and is therefore an eco-friendly alternative to the existing methods.
