109063-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109063-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,6 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109063-59:
(8*1)+(7*0)+(6*9)+(5*0)+(4*6)+(3*3)+(2*5)+(1*9)=114
114 % 10 = 4
So 109063-59-4 is a valid CAS Registry Number.
