The CAS Registry Mumber 129658-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,5 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129658-44:
(8*1)+(7*2)+(6*9)+(5*6)+(4*5)+(3*8)+(2*4)+(1*4)=162
162 % 10 = 2
