669776-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 669776-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,7,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 669776-99:
(8*6)+(7*6)+(6*9)+(5*7)+(4*7)+(3*6)+(2*9)+(1*9)=252
252 % 10 = 2
So 669776-99-2 is a valid CAS Registry Number.
