Check Digit Verification of cas no

The CAS Registry Mumber 6857-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6857-81:
(6*6)+(5*8)+(4*5)+(3*7)+(2*8)+(1*1)=134
134 % 10 = 4
So 6857-81-4 is a valid CAS Registry Number.
