250291-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250291-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,2,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 250291-63:
(8*2)+(7*5)+(6*0)+(5*2)+(4*9)+(3*1)+(2*6)+(1*3)=115
115 % 10 = 5
So 250291-63-5 is a valid CAS Registry Number.
