252289-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252289-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,2,8 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 252289-77:
(8*2)+(7*5)+(6*2)+(5*2)+(4*8)+(3*9)+(2*7)+(1*7)=153
153 % 10 = 3
So 252289-77-3 is a valid CAS Registry Number.
