Check Digit Verification of cas no

The CAS Registry Mumber 159715-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,1 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159715-20:
(8*1)+(7*5)+(6*9)+(5*7)+(4*1)+(3*5)+(2*2)+(1*0)=155
155 % 10 = 5
So 159715-20-5 is a valid CAS Registry Number.

Majewska, Paulina,Doskocz, Marek,Lejczak, Barbara,Kafarski, Pawel

experimental part, p. 1568 - 1574 (2009/11/30)

The use of quinine as a chiral solvating agent allows us to determine a tentative absolute configuration at the phosphorus atom of hydroxyphosphinates with two stereogenic centres (at the phosphorus and α-carbon atoms). Two ethyl butyryloxyalkane(P-phenyl
