116991-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116991-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,9 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116991-24:
(8*1)+(7*1)+(6*6)+(5*9)+(4*9)+(3*1)+(2*2)+(1*4)=143
143 % 10 = 3
So 116991-24-3 is a valid CAS Registry Number.
