Check Digit Verification of cas no

The CAS Registry Mumber 19988-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,8 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19988-54:
(7*1)+(6*9)+(5*9)+(4*8)+(3*8)+(2*5)+(1*4)=176
176 % 10 = 6
So 19988-54-6 is a valid CAS Registry Number.
