Check Digit Verification of cas no
The CAS Registry Mumber 49559-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,5,5 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 49559-65:
(7*4)+(6*9)+(5*5)+(4*5)+(3*9)+(2*6)+(1*5)=171
171 % 10 = 1
So 49559-65-1 is a valid CAS Registry Number.
