331813-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 331813-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,8,1 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 331813-58:
(8*3)+(7*3)+(6*1)+(5*8)+(4*1)+(3*3)+(2*5)+(1*8)=122
122 % 10 = 2
So 331813-58-2 is a valid CAS Registry Number.
