70508-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70508-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70508-53:
(7*7)+(6*0)+(5*5)+(4*0)+(3*8)+(2*5)+(1*3)=111
111 % 10 = 1
So 70508-53-1 is a valid CAS Registry Number.
