113769-79-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113769-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,7,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113769-79:
(8*1)+(7*1)+(6*3)+(5*7)+(4*6)+(3*9)+(2*7)+(1*9)=142
142 % 10 = 2
So 113769-79-2 is a valid CAS Registry Number.
