55821-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55821-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55821-40:
(7*5)+(6*5)+(5*8)+(4*2)+(3*1)+(2*4)+(1*0)=124
124 % 10 = 4
So 55821-40-4 is a valid CAS Registry Number.
