Check Digit Verification of cas no
The CAS Registry Mumber 337468-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,4,6 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 337468-25:
(8*3)+(7*3)+(6*7)+(5*4)+(4*6)+(3*8)+(2*2)+(1*5)=164
164 % 10 = 4
So 337468-25-4 is a valid CAS Registry Number.
