Check Digit Verification of cas no
The CAS Registry Mumber 23451-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,5 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23451-62:
(7*2)+(6*3)+(5*4)+(4*5)+(3*1)+(2*6)+(1*2)=89
89 % 10 = 9
So 23451-62-9 is a valid CAS Registry Number.
