Check Digit Verification of cas no

The CAS Registry Mumber 1581699-73-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,6,9 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1581699-73:
(9*1)+(8*5)+(7*8)+(6*1)+(5*6)+(4*9)+(3*9)+(2*7)+(1*3)=221
221 % 10 = 1
So 1581699-73-1 is a valid CAS Registry Number.
