6772-80-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6772-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6772-80:
(6*6)+(5*7)+(4*7)+(3*2)+(2*8)+(1*0)=121
121 % 10 = 1
So 6772-80-1 is a valid CAS Registry Number.
