712282-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 712282-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,2,2,8 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 712282-28:
(8*7)+(7*1)+(6*2)+(5*2)+(4*8)+(3*2)+(2*2)+(1*8)=135
135 % 10 = 5
So 712282-28-5 is a valid CAS Registry Number.
