126256-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126256-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,2,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126256-71:
(8*1)+(7*2)+(6*6)+(5*2)+(4*5)+(3*6)+(2*7)+(1*1)=121
121 % 10 = 1
So 126256-71-1 is a valid CAS Registry Number.
