1178563-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1178563-01-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,8,5,6 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1178563-01:
(9*1)+(8*1)+(7*7)+(6*8)+(5*5)+(4*6)+(3*3)+(2*0)+(1*1)=173
173 % 10 = 3
So 1178563-01-3 is a valid CAS Registry Number.
