285992-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 285992-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,5,9,9 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 285992-99:
(8*2)+(7*8)+(6*5)+(5*9)+(4*9)+(3*2)+(2*9)+(1*9)=216
216 % 10 = 6
So 285992-99-6 is a valid CAS Registry Number.
