The CAS Registry Mumber 1268341-29-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,3,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1268341-29:
(9*1)+(8*2)+(7*6)+(6*8)+(5*3)+(4*4)+(3*1)+(2*2)+(1*9)=162
162 % 10 = 2
So 1268341-29-2 is a valid CAS Registry Number.
