Check Digit Verification of cas no

The CAS Registry Mumber 20561-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,6 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20561-89:
(7*2)+(6*0)+(5*5)+(4*6)+(3*1)+(2*8)+(1*9)=91
91 % 10 = 1
So 20561-89-1 is a valid CAS Registry Number.
