77053-66-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77053-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,5 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77053-66:
(7*7)+(6*7)+(5*0)+(4*5)+(3*3)+(2*6)+(1*6)=138
138 % 10 = 8
So 77053-66-8 is a valid CAS Registry Number.
