Check Digit Verification of cas no
The CAS Registry Mumber 72804-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,0 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72804-49:
(7*7)+(6*2)+(5*8)+(4*0)+(3*4)+(2*4)+(1*9)=130
130 % 10 = 0
So 72804-49-0 is a valid CAS Registry Number.
