1451051-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1451051-50-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,1,0,5 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1451051-50:
(9*1)+(8*4)+(7*5)+(6*1)+(5*0)+(4*5)+(3*1)+(2*5)+(1*0)=115
115 % 10 = 5
So 1451051-50-5 is a valid CAS Registry Number.
