852568-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 852568-72-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,2,5,6 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 852568-72:
(8*8)+(7*5)+(6*2)+(5*5)+(4*6)+(3*8)+(2*7)+(1*2)=200
200 % 10 = 0
So 852568-72-0 is a valid CAS Registry Number.
