Check Digit Verification of cas no
The CAS Registry Mumber 228270-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,2,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228270-72:
(8*2)+(7*2)+(6*8)+(5*2)+(4*7)+(3*0)+(2*7)+(1*2)=132
132 % 10 = 2
So 228270-72-2 is a valid CAS Registry Number.
