117998-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117998-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,9 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117998-92:
(8*1)+(7*1)+(6*7)+(5*9)+(4*9)+(3*8)+(2*9)+(1*2)=182
182 % 10 = 2
So 117998-92-2 is a valid CAS Registry Number.
