1026189-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026189-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,1,8 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1026189-68:
(9*1)+(8*0)+(7*2)+(6*6)+(5*1)+(4*8)+(3*9)+(2*6)+(1*8)=143
143 % 10 = 3
So 1026189-68-3 is a valid CAS Registry Number.
