77778-18-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77778-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,7 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77778-18:
(7*7)+(6*7)+(5*7)+(4*7)+(3*8)+(2*1)+(1*8)=188
188 % 10 = 8
So 77778-18-8 is a valid CAS Registry Number.
