The CAS Registry Mumber 207804-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,8,0 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 207804-01:
(8*2)+(7*0)+(6*7)+(5*8)+(4*0)+(3*4)+(2*0)+(1*1)=111
111 % 10 = 1
So 207804-01-1 is a valid CAS Registry Number.
