79240-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79240-22-5 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 79240-22:
(7*7)+(6*9)+(5*2)+(4*4)+(3*0)+(2*2)+(1*2)=135
135 % 10 = 5
So 79240-22-5 is a valid CAS Registry Number.
