Check Digit Verification of cas no

The CAS Registry Mumber 1621525-09-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,5,2 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1621525-09:
(9*1)+(8*6)+(7*2)+(6*1)+(5*5)+(4*2)+(3*5)+(2*0)+(1*9)=134
134 % 10 = 4
So 1621525-09-4 is a valid CAS Registry Number.
