250689-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250689-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,6,8 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 250689-53:
(8*2)+(7*5)+(6*0)+(5*6)+(4*8)+(3*9)+(2*5)+(1*3)=153
153 % 10 = 3
So 250689-53-3 is a valid CAS Registry Number.
