Check Digit Verification of cas no
The CAS Registry Mumber 5406-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,0 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5406-65:
(6*5)+(5*4)+(4*0)+(3*6)+(2*6)+(1*5)=85
85 % 10 = 5
So 5406-65-5 is a valid CAS Registry Number.
