The CAS Registry Mumber 861920-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,9,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 861920-98:
(8*8)+(7*6)+(6*1)+(5*9)+(4*2)+(3*0)+(2*9)+(1*8)=191
191 % 10 = 1
So 861920-98-1 is a valid CAS Registry Number.
