55294-88-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55294-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,9 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55294-88:
(7*5)+(6*5)+(5*2)+(4*9)+(3*4)+(2*8)+(1*8)=147
147 % 10 = 7
So 55294-88-7 is a valid CAS Registry Number.
