Check Digit Verification of cas no
The CAS Registry Mumber 23238-59-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23238-59:
(7*2)+(6*3)+(5*2)+(4*3)+(3*8)+(2*5)+(1*9)=97
97 % 10 = 7
So 23238-59-7 is a valid CAS Registry Number.
