142559-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142559-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,5 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142559-95:
(8*1)+(7*4)+(6*2)+(5*5)+(4*5)+(3*9)+(2*9)+(1*5)=143
143 % 10 = 3
So 142559-95-3 is a valid CAS Registry Number.
