3456-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3456-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 3456-71:
(6*3)+(5*4)+(4*5)+(3*6)+(2*7)+(1*1)=91
91 % 10 = 1
So 3456-71-1 is a valid CAS Registry Number.
