Check Digit Verification of cas no
The CAS Registry Mumber 55994-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,9 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55994-13:
(7*5)+(6*5)+(5*9)+(4*9)+(3*4)+(2*1)+(1*3)=163
163 % 10 = 3
So 55994-13-3 is a valid CAS Registry Number.
