1026054-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026054-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,0,5 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1026054-90:
(9*1)+(8*0)+(7*2)+(6*6)+(5*0)+(4*5)+(3*4)+(2*9)+(1*0)=109
109 % 10 = 9
So 1026054-90-9 is a valid CAS Registry Number.
