1028333-64-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1028333-64-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,3,3 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1028333-64:
(9*1)+(8*0)+(7*2)+(6*8)+(5*3)+(4*3)+(3*3)+(2*6)+(1*4)=123
123 % 10 = 3
So 1028333-64-3 is a valid CAS Registry Number.
