Check Digit Verification of cas no

The CAS Registry Mumber 70925-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,2 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70925-57:
(7*7)+(6*0)+(5*9)+(4*2)+(3*5)+(2*5)+(1*7)=134
134 % 10 = 4
So 70925-57-4 is a valid CAS Registry Number.
