91887-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91887-26-2 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, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91887-26:
(7*9)+(6*1)+(5*8)+(4*8)+(3*7)+(2*2)+(1*6)=172
172 % 10 = 2
So 91887-26-2 is a valid CAS Registry Number.
