27778-66-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27778-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,7 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 27778-66:
(7*2)+(6*7)+(5*7)+(4*7)+(3*8)+(2*6)+(1*6)=161
161 % 10 = 1
So 27778-66-1 is a valid CAS Registry Number.
