254909-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 254909-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,9,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 254909-21:
(8*2)+(7*5)+(6*4)+(5*9)+(4*0)+(3*9)+(2*2)+(1*1)=152
152 % 10 = 2
So 254909-21-2 is a valid CAS Registry Number.
