Check Digit Verification of cas no
The CAS Registry Mumber 439937-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,9,3 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 439937-54:
(8*4)+(7*3)+(6*9)+(5*9)+(4*3)+(3*7)+(2*5)+(1*4)=199
199 % 10 = 9
So 439937-54-9 is a valid CAS Registry Number.
