The CAS Registry Mumber 91026-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,2 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91026-33:
(7*9)+(6*1)+(5*0)+(4*2)+(3*6)+(2*3)+(1*3)=104
104 % 10 = 4
So 91026-33-4 is a valid CAS Registry Number.
