561306-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 561306-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,1,3,0 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 561306-28:
(8*5)+(7*6)+(6*1)+(5*3)+(4*0)+(3*6)+(2*2)+(1*8)=133
133 % 10 = 3
So 561306-28-3 is a valid CAS Registry Number.
