3891-25-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3891-25-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.Calculate Digit Verification of CAS Registry Number 3891-25:
(6*3)+(5*8)+(4*9)+(3*1)+(2*2)+(1*5)=106
106 % 10 = 6
So 3891-25-6 is a valid CAS Registry Number.
