126773-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126773-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,7 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 126773-55:
(8*1)+(7*2)+(6*6)+(5*7)+(4*7)+(3*3)+(2*5)+(1*5)=145
145 % 10 = 5
So 126773-55-5 is a valid CAS Registry Number.
