126538-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126538-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,3 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126538-68:
(8*1)+(7*2)+(6*6)+(5*5)+(4*3)+(3*8)+(2*6)+(1*8)=139
139 % 10 = 9
So 126538-68-9 is a valid CAS Registry Number.
