88931-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88931-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,9,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 88931-34:
(7*8)+(6*8)+(5*9)+(4*3)+(3*1)+(2*3)+(1*4)=174
174 % 10 = 4
So 88931-34-4 is a valid CAS Registry Number.
