The CAS Registry Mumber 142906-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,0 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142906-20:
(8*1)+(7*4)+(6*2)+(5*9)+(4*0)+(3*6)+(2*2)+(1*0)=115
115 % 10 = 5
So 142906-20-5 is a valid CAS Registry Number.
