116114-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116114-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,1 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116114-71:
(8*1)+(7*1)+(6*6)+(5*1)+(4*1)+(3*4)+(2*7)+(1*1)=87
87 % 10 = 7
So 116114-71-7 is a valid CAS Registry Number.
