The CAS Registry Mumber 557794-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,7,9 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 557794-39:
(8*5)+(7*5)+(6*7)+(5*7)+(4*9)+(3*4)+(2*3)+(1*9)=215
215 % 10 = 5
So 557794-39-5 is a valid CAS Registry Number.
