117873-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117873-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,7 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117873-75:
(8*1)+(7*1)+(6*7)+(5*8)+(4*7)+(3*3)+(2*7)+(1*5)=153
153 % 10 = 3
So 117873-75-3 is a valid CAS Registry Number.
