Check Digit Verification of cas no

The CAS Registry Mumber 1570216-19-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,0,2,1 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1570216-19:
(9*1)+(8*5)+(7*7)+(6*0)+(5*2)+(4*1)+(3*6)+(2*1)+(1*9)=141
141 % 10 = 1
So 1570216-19-1 is a valid CAS Registry Number.
