91483-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91483-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,8 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91483-45:
(7*9)+(6*1)+(5*4)+(4*8)+(3*3)+(2*4)+(1*5)=143
143 % 10 = 3
So 91483-45-3 is a valid CAS Registry Number.
