Check Digit Verification of cas no

The CAS Registry Mumber 1645-26-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1645-26:
(6*1)+(5*6)+(4*4)+(3*5)+(2*2)+(1*6)=77
77 % 10 = 7
So 1645-26-7 is a valid CAS Registry Number.
