Check Digit Verification of cas no
The CAS Registry Mumber 467234-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,7,2,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 467234-67:
(8*4)+(7*6)+(6*7)+(5*2)+(4*3)+(3*4)+(2*6)+(1*7)=169
169 % 10 = 9
So 467234-67-9 is a valid CAS Registry Number.
