850255-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850255-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,2,5 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 850255-05:
(8*8)+(7*5)+(6*0)+(5*2)+(4*5)+(3*5)+(2*0)+(1*5)=149
149 % 10 = 9
So 850255-05-9 is a valid CAS Registry Number.
