579472-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 579472-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,9,4,7 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 579472-21:
(8*5)+(7*7)+(6*9)+(5*4)+(4*7)+(3*2)+(2*2)+(1*1)=202
202 % 10 = 2
So 579472-21-2 is a valid CAS Registry Number.
