117321-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117321-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,3,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117321-76:
(8*1)+(7*1)+(6*7)+(5*3)+(4*2)+(3*1)+(2*7)+(1*6)=103
103 % 10 = 3
So 117321-76-3 is a valid CAS Registry Number.
