91887-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91887-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,8 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91887-19:
(7*9)+(6*1)+(5*8)+(4*8)+(3*7)+(2*1)+(1*9)=173
173 % 10 = 3
So 91887-19-3 is a valid CAS Registry Number.
