Check Digit Verification of cas no

The CAS Registry Mumber 5418-37-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5418-37:
(6*5)+(5*4)+(4*1)+(3*8)+(2*3)+(1*7)=91
91 % 10 = 1
So 5418-37-1 is a valid CAS Registry Number.
