142501-54-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142501-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,0 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142501-54:
(8*1)+(7*4)+(6*2)+(5*5)+(4*0)+(3*1)+(2*5)+(1*4)=90
90 % 10 = 0
So 142501-54-0 is a valid CAS Registry Number.
