551920-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 551920-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,1,9,2 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 551920-21:
(8*5)+(7*5)+(6*1)+(5*9)+(4*2)+(3*0)+(2*2)+(1*1)=139
139 % 10 = 9
So 551920-21-9 is a valid CAS Registry Number.
