102259-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102259-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,5 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 102259-10:
(8*1)+(7*0)+(6*2)+(5*2)+(4*5)+(3*9)+(2*1)+(1*0)=79
79 % 10 = 9
So 102259-10-9 is a valid CAS Registry Number.
