673456-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 673456-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,3,4,5 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 673456-35:
(8*6)+(7*7)+(6*3)+(5*4)+(4*5)+(3*6)+(2*3)+(1*5)=184
184 % 10 = 4
So 673456-35-4 is a valid CAS Registry Number.
