Check Digit Verification of cas no

The CAS Registry Mumber 31375-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,7 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31375-19:
(7*3)+(6*1)+(5*3)+(4*7)+(3*5)+(2*1)+(1*9)=96
96 % 10 = 6
So 31375-19-6 is a valid CAS Registry Number.
