4990-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4990-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 4990-91:
(6*4)+(5*9)+(4*9)+(3*0)+(2*9)+(1*1)=124
124 % 10 = 4
So 4990-91-4 is a valid CAS Registry Number.
