Check Digit Verification of cas no
The CAS Registry Mumber 33868-03-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,6 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33868-03:
(7*3)+(6*3)+(5*8)+(4*6)+(3*8)+(2*0)+(1*3)=130
130 % 10 = 0
So 33868-03-0 is a valid CAS Registry Number.
