Check Digit Verification of cas no
The CAS Registry Mumber 149725-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,7,2 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 149725-81:
(8*1)+(7*4)+(6*9)+(5*7)+(4*2)+(3*5)+(2*8)+(1*1)=165
165 % 10 = 5
So 149725-81-5 is a valid CAS Registry Number.
