Check Digit Verification of cas no

The CAS Registry Mumber 1773-41-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1773-41:
(6*1)+(5*7)+(4*7)+(3*3)+(2*4)+(1*1)=87
87 % 10 = 7
So 1773-41-7 is a valid CAS Registry Number.
