55985-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55985-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,8 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55985-31:
(7*5)+(6*5)+(5*9)+(4*8)+(3*5)+(2*3)+(1*1)=164
164 % 10 = 4
So 55985-31-4 is a valid CAS Registry Number.
