67346-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67346-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,4 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67346-51:
(7*6)+(6*7)+(5*3)+(4*4)+(3*6)+(2*5)+(1*1)=144
144 % 10 = 4
So 67346-51-4 is a valid CAS Registry Number.
