Check Digit Verification of cas no
The CAS Registry Mumber 18724-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,2 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18724-73:
(7*1)+(6*8)+(5*7)+(4*2)+(3*4)+(2*7)+(1*3)=127
127 % 10 = 7
So 18724-73-7 is a valid CAS Registry Number.
