The CAS Registry Mumber 1129427-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,4,2 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1129427-90:
(9*1)+(8*1)+(7*2)+(6*9)+(5*4)+(4*2)+(3*7)+(2*9)+(1*0)=152
152 % 10 = 2
