116897-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116897-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,8,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116897-69:
(8*1)+(7*1)+(6*6)+(5*8)+(4*9)+(3*7)+(2*6)+(1*9)=169
169 % 10 = 9
So 116897-69-9 is a valid CAS Registry Number.
