Check Digit Verification of cas no

The CAS Registry Mumber 17055-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,5 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17055-50:
(7*1)+(6*7)+(5*0)+(4*5)+(3*5)+(2*5)+(1*0)=94
94 % 10 = 4
So 17055-50-4 is a valid CAS Registry Number.
