The CAS Registry Mumber 137303-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137303-38:
(8*1)+(7*3)+(6*7)+(5*3)+(4*0)+(3*3)+(2*3)+(1*8)=109
109 % 10 = 9
So 137303-38-9 is a valid CAS Registry Number.
