145572-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145572-50-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,5,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145572-50:
(8*1)+(7*4)+(6*5)+(5*5)+(4*7)+(3*2)+(2*5)+(1*0)=135
135 % 10 = 5
So 145572-50-5 is a valid CAS Registry Number.
