Check Digit Verification of cas no

The CAS Registry Mumber 1157865-90-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,7,8,6 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1157865-90:
(9*1)+(8*1)+(7*5)+(6*7)+(5*8)+(4*6)+(3*5)+(2*9)+(1*0)=191
191 % 10 = 1
So 1157865-90-1 is a valid CAS Registry Number.
