The CAS Registry Mumber 201533-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,5,3 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201533-38:
(8*2)+(7*0)+(6*1)+(5*5)+(4*3)+(3*3)+(2*3)+(1*8)=82
82 % 10 = 2
So 201533-38-2 is a valid CAS Registry Number.
