Check Digit Verification of cas no

The CAS Registry Mumber 3891-40-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3891-40:
(6*3)+(5*8)+(4*9)+(3*1)+(2*4)+(1*0)=105
105 % 10 = 5
So 3891-40-5 is a valid CAS Registry Number.
