56890-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56890-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,9 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56890-40:
(7*5)+(6*6)+(5*8)+(4*9)+(3*0)+(2*4)+(1*0)=155
155 % 10 = 5
So 56890-40-5 is a valid CAS Registry Number.
