The CAS Registry Mumber 91653-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,5 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91653-27:
(7*9)+(6*1)+(5*6)+(4*5)+(3*3)+(2*2)+(1*7)=139
139 % 10 = 9
So 91653-27-9 is a valid CAS Registry Number.
