31519-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31519-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31519-30:
(7*3)+(6*1)+(5*5)+(4*1)+(3*9)+(2*3)+(1*0)=89
89 % 10 = 9
So 31519-30-9 is a valid CAS Registry Number.
