Check Digit Verification of cas no
The CAS Registry Mumber 468743-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,8,7,4 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 468743-81:
(8*4)+(7*6)+(6*8)+(5*7)+(4*4)+(3*3)+(2*8)+(1*1)=199
199 % 10 = 9
So 468743-81-9 is a valid CAS Registry Number.
