Check Digit Verification of cas no

The CAS Registry Mumber 56643-53-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,4 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 56643-53:
(7*5)+(6*6)+(5*6)+(4*4)+(3*3)+(2*5)+(1*3)=139
139 % 10 = 9
So 56643-53-9 is a valid CAS Registry Number.
