Check Digit Verification of cas no

The CAS Registry Mumber 37174-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,1,7 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37174-98:
(7*3)+(6*7)+(5*1)+(4*7)+(3*4)+(2*9)+(1*8)=134
134 % 10 = 4
So 37174-98-4 is a valid CAS Registry Number.
