126454-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126454-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,5 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126454-97:
(8*1)+(7*2)+(6*6)+(5*4)+(4*5)+(3*4)+(2*9)+(1*7)=135
135 % 10 = 5
So 126454-97-5 is a valid CAS Registry Number.
