55649-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55649-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55649-81:
(7*5)+(6*5)+(5*6)+(4*4)+(3*9)+(2*8)+(1*1)=155
155 % 10 = 5
So 55649-81-5 is a valid CAS Registry Number.
