The CAS Registry Mumber 72917-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72917-40:
(7*7)+(6*2)+(5*9)+(4*1)+(3*7)+(2*4)+(1*0)=139
139 % 10 = 9
