3430-64-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3430-64-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,3 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.Calculate Digit Verification of CAS Registry Number 3430-64:
(6*3)+(5*4)+(4*3)+(3*0)+(2*6)+(1*4)=66
66 % 10 = 6
So 3430-64-6 is a valid CAS Registry Number.
