91887-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91887-22-8 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 91887-22:
(7*9)+(6*1)+(5*8)+(4*8)+(3*7)+(2*2)+(1*2)=168
168 % 10 = 8
So 91887-22-8 is a valid CAS Registry Number.
