142034-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142034-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,3 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142034-35:
(8*1)+(7*4)+(6*2)+(5*0)+(4*3)+(3*4)+(2*3)+(1*5)=83
83 % 10 = 3
So 142034-35-3 is a valid CAS Registry Number.
