Check Digit Verification of cas no
The CAS Registry Mumber 72870-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,7 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 72870-78:
(7*7)+(6*2)+(5*8)+(4*7)+(3*0)+(2*7)+(1*8)=151
151 % 10 = 1
So 72870-78-1 is a valid CAS Registry Number.
