67265-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67265-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,6 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.Calculate Digit Verification of CAS Registry Number 67265-01:
(7*6)+(6*7)+(5*2)+(4*6)+(3*5)+(2*0)+(1*1)=134
134 % 10 = 4
So 67265-01-4 is a valid CAS Registry Number.
