Chemical Properties

beige to grey-brown crystalline powder

Check Digit Verification of cas no

The CAS Registry Mumber 68460-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,6 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68460-01:
(7*6)+(6*8)+(5*4)+(4*6)+(3*0)+(2*0)+(1*1)=135
135 % 10 = 5
So 68460-01-5 is a valid CAS Registry Number.
