Check Digit Verification of cas no
The CAS Registry Mumber 31368-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,6 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31368-33:
(7*3)+(6*1)+(5*3)+(4*6)+(3*8)+(2*3)+(1*3)=99
99 % 10 = 9
So 31368-33-9 is a valid CAS Registry Number.
