Check Digit Verification of cas no
The CAS Registry Mumber 3567-65-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3567-65:
(6*3)+(5*5)+(4*6)+(3*7)+(2*6)+(1*5)=105
105 % 10 = 5
So 3567-65-5 is a valid CAS Registry Number.
