126456-01-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126456-01-7 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 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126456-01:
(8*1)+(7*2)+(6*6)+(5*4)+(4*5)+(3*6)+(2*0)+(1*1)=117
117 % 10 = 7
So 126456-01-7 is a valid CAS Registry Number.
