Check Digit Verification of cas no
The CAS Registry Mumber 170028-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,0,2 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 170028-11:
(8*1)+(7*7)+(6*0)+(5*0)+(4*2)+(3*8)+(2*1)+(1*1)=92
92 % 10 = 2
So 170028-11-2 is a valid CAS Registry Number.
