Check Digit Verification of cas no
The CAS Registry Mumber 87592-00-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,9 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87592-00:
(7*8)+(6*7)+(5*5)+(4*9)+(3*2)+(2*0)+(1*0)=165
165 % 10 = 5
So 87592-00-5 is a valid CAS Registry Number.
