Check Digit Verification of cas no
The CAS Registry Mumber 872143-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,1,4 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 872143-57:
(8*8)+(7*7)+(6*2)+(5*1)+(4*4)+(3*3)+(2*5)+(1*7)=172
172 % 10 = 2
So 872143-57-2 is a valid CAS Registry Number.
