77149-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77149-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,4 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77149-13:
(7*7)+(6*7)+(5*1)+(4*4)+(3*9)+(2*1)+(1*3)=144
144 % 10 = 4
So 77149-13-4 is a valid CAS Registry Number.
