Check Digit Verification of cas no
The CAS Registry Mumber 13355-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,5 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13355-59:
(7*1)+(6*3)+(5*3)+(4*5)+(3*5)+(2*5)+(1*9)=94
94 % 10 = 4
So 13355-59-4 is a valid CAS Registry Number.
