126522-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126522-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,5,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126522-80:
(8*1)+(7*2)+(6*6)+(5*5)+(4*2)+(3*2)+(2*8)+(1*0)=113
113 % 10 = 3
So 126522-80-3 is a valid CAS Registry Number.
