Check Digit Verification of cas no

The CAS Registry Mumber 67253-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,5 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67253-70:
(7*6)+(6*7)+(5*2)+(4*5)+(3*3)+(2*7)+(1*0)=137
137 % 10 = 7
So 67253-70-7 is a valid CAS Registry Number.
