339570-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 339570-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,5,7 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 339570-92:
(8*3)+(7*3)+(6*9)+(5*5)+(4*7)+(3*0)+(2*9)+(1*2)=172
172 % 10 = 2
So 339570-92-2 is a valid CAS Registry Number.
