4981-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4981-32-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 4981-32:
(6*4)+(5*9)+(4*8)+(3*1)+(2*3)+(1*2)=112
112 % 10 = 2
So 4981-32-2 is a valid CAS Registry Number.
