126741-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126741-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,4 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126741-65:
(8*1)+(7*2)+(6*6)+(5*7)+(4*4)+(3*1)+(2*6)+(1*5)=129
129 % 10 = 9
So 126741-65-9 is a valid CAS Registry Number.
