5891-83-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5891-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5891-83:
(6*5)+(5*8)+(4*9)+(3*1)+(2*8)+(1*3)=128
128 % 10 = 8
So 5891-83-8 is a valid CAS Registry Number.
