98315-34-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98315-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,1 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98315-34:
(7*9)+(6*8)+(5*3)+(4*1)+(3*5)+(2*3)+(1*4)=155
155 % 10 = 5
So 98315-34-5 is a valid CAS Registry Number.
