Check Digit Verification of cas no

The CAS Registry Mumber 53708-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,0 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53708-50:
(7*5)+(6*3)+(5*7)+(4*0)+(3*8)+(2*5)+(1*0)=122
122 % 10 = 2
So 53708-50-2 is a valid CAS Registry Number.
