Check Digit Verification of cas no

The CAS Registry Mumber 171234-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,2,3 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 171234-88:
(8*1)+(7*7)+(6*1)+(5*2)+(4*3)+(3*4)+(2*8)+(1*8)=121
121 % 10 = 1
So 171234-88-1 is a valid CAS Registry Number.
