117563-17-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117563-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,6 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117563-17:
(8*1)+(7*1)+(6*7)+(5*5)+(4*6)+(3*3)+(2*1)+(1*7)=124
124 % 10 = 4
So 117563-17-4 is a valid CAS Registry Number.
