The CAS Registry Mumber 188910-76-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,1 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188910-76:
(8*1)+(7*8)+(6*8)+(5*9)+(4*1)+(3*0)+(2*7)+(1*6)=181
181 % 10 = 1
So 188910-76-1 is a valid CAS Registry Number.
