Check Digit Verification of cas no
The CAS Registry Mumber 70724-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,7,2 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70724-23:
(7*7)+(6*0)+(5*7)+(4*2)+(3*4)+(2*2)+(1*3)=111
111 % 10 = 1
So 70724-23-1 is a valid CAS Registry Number.
