111897-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111897-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,8,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 111897-93:
(8*1)+(7*1)+(6*1)+(5*8)+(4*9)+(3*7)+(2*9)+(1*3)=139
139 % 10 = 9
So 111897-93-9 is a valid CAS Registry Number.
