The CAS Registry Mumber 134891-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,9 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134891-93:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*1)+(2*9)+(1*3)=153
153 % 10 = 3
So 134891-93-3 is a valid CAS Registry Number.
