3889-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3889-56-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,8 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 3889-56:
(6*3)+(5*8)+(4*8)+(3*9)+(2*5)+(1*6)=133
133 % 10 = 3
So 3889-56-3 is a valid CAS Registry Number.
