17761-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17761-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,6 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 17761-23:
(7*1)+(6*7)+(5*7)+(4*6)+(3*1)+(2*2)+(1*3)=118
118 % 10 = 8
So 17761-23-8 is a valid CAS Registry Number.
