Check Digit Verification of cas no

The CAS Registry Mumber 5740-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5740-26:
(6*5)+(5*7)+(4*4)+(3*0)+(2*2)+(1*6)=91
91 % 10 = 1
So 5740-26-1 is a valid CAS Registry Number.
