Check Digit Verification of cas no

The CAS Registry Mumber 5891-57-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5891-57:
(6*5)+(5*8)+(4*9)+(3*1)+(2*5)+(1*7)=126
126 % 10 = 6
So 5891-57-6 is a valid CAS Registry Number.
