434336-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 434336-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,4,3,3 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 434336-19:
(8*4)+(7*3)+(6*4)+(5*3)+(4*3)+(3*6)+(2*1)+(1*9)=133
133 % 10 = 3
So 434336-19-3 is a valid CAS Registry Number.
