333399-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 333399-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,3,9 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 333399-52:
(8*3)+(7*3)+(6*3)+(5*3)+(4*9)+(3*9)+(2*5)+(1*2)=153
153 % 10 = 3
So 333399-52-3 is a valid CAS Registry Number.
