5591-12-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5591-12-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,9 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5591-12:
(6*5)+(5*5)+(4*9)+(3*1)+(2*1)+(1*2)=98
98 % 10 = 8
So 5591-12-8 is a valid CAS Registry Number.
