The CAS Registry Mumber 1286736-28-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,3 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1286736-28:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*3)+(3*6)+(2*2)+(1*8)=194
194 % 10 = 4
