256509-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 256509-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,5,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 256509-99:
(8*2)+(7*5)+(6*6)+(5*5)+(4*0)+(3*9)+(2*9)+(1*9)=166
166 % 10 = 6
So 256509-99-6 is a valid CAS Registry Number.
