77542-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77542-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,4 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77542-04:
(7*7)+(6*7)+(5*5)+(4*4)+(3*2)+(2*0)+(1*4)=142
142 % 10 = 2
So 77542-04-2 is a valid CAS Registry Number.
