Check Digit Verification of cas no

The CAS Registry Mumber 20745-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,4 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20745-47:
(7*2)+(6*0)+(5*7)+(4*4)+(3*5)+(2*4)+(1*7)=95
95 % 10 = 5
So 20745-47-5 is a valid CAS Registry Number.
