Check Digit Verification of cas no
The CAS Registry Mumber 21938-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,3 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21938-23:
(7*2)+(6*1)+(5*9)+(4*3)+(3*8)+(2*2)+(1*3)=108
108 % 10 = 8
So 21938-23-8 is a valid CAS Registry Number.
