55687-63-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55687-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,8 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55687-63:
(7*5)+(6*5)+(5*6)+(4*8)+(3*7)+(2*6)+(1*3)=163
163 % 10 = 3
So 55687-63-3 is a valid CAS Registry Number.
