Check Digit Verification of cas no

The CAS Registry Mumber 52053-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,5 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52053-97:
(7*5)+(6*2)+(5*0)+(4*5)+(3*3)+(2*9)+(1*7)=101
101 % 10 = 1
So 52053-97-1 is a valid CAS Registry Number.
