Check Digit Verification of cas no

The CAS Registry Mumber 59643-57-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,6,4 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 59643-57:
(7*5)+(6*9)+(5*6)+(4*4)+(3*3)+(2*5)+(1*7)=161
161 % 10 = 1
So 59643-57-1 is a valid CAS Registry Number.
