79240-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79240-28-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,4 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79240-28:
(7*7)+(6*9)+(5*2)+(4*4)+(3*0)+(2*2)+(1*8)=141
141 % 10 = 1
So 79240-28-1 is a valid CAS Registry Number.
