49773-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49773-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,7 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 49773-39:
(7*4)+(6*9)+(5*7)+(4*7)+(3*3)+(2*3)+(1*9)=169
169 % 10 = 9
So 49773-39-9 is a valid CAS Registry Number.
