Check Digit Verification of cas no

The CAS Registry Mumber 1571900-35-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,1,9,0 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1571900-35:
(9*1)+(8*5)+(7*7)+(6*1)+(5*9)+(4*0)+(3*0)+(2*3)+(1*5)=160
160 % 10 = 0
So 1571900-35-0 is a valid CAS Registry Number.

Gold-catalyzed hydroarylation of aryl alkynylphosphonates for the synthesis of phosphacoumarins

Kim, Cheol-Eui,Ryu, Taekyu,Kim, Sanghyuck,Lee, Kooyeon,Lee, Chang-Hee,Lee, Phil Ho

, p. 2873 - 2883 (2014/03/21)

Intramolecular hydroarylation using aryl alkynylphosphonates proceeds smoothly with a gold/ silver catalyst in the presence of trifluoromethanesulfonic acid (TfOH) in the 6-endo mode, thus affording a unique synthetic method for phosphacoumarins having various functional groups, which could be a privileged structure and prevalent scaffold in phosphorus heterocycles.
