1026-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1026-55:
(6*1)+(5*0)+(4*2)+(3*6)+(2*5)+(1*5)=47
47 % 10 = 7
So 1026-55-7 is a valid CAS Registry Number.
