70528-90-4 Usage
Flammability and Explosibility
NonflammableCheck Digit Verification of cas no
The CAS Registry Mumber 70528-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,2 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.Calculate Digit Verification of CAS Registry Number 70528-90:
(7*7)+(6*0)+(5*5)+(4*2)+(3*8)+(2*9)+(1*0)=124
124 % 10 = 4
So 70528-90-4 is a valid CAS Registry Number.
