142335-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142335-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,3 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142335-29:
(8*1)+(7*4)+(6*2)+(5*3)+(4*3)+(3*5)+(2*2)+(1*9)=103
103 % 10 = 3
So 142335-29-3 is a valid CAS Registry Number.
