The CAS Registry Mumber 83990-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,9 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83990-23:
(7*8)+(6*3)+(5*9)+(4*9)+(3*0)+(2*2)+(1*3)=162
162 % 10 = 2
So 83990-23-2 is a valid CAS Registry Number.
