199385-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199385-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,3,8 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 199385-28:
(8*1)+(7*9)+(6*9)+(5*3)+(4*8)+(3*5)+(2*2)+(1*8)=199
199 % 10 = 9
So 199385-28-9 is a valid CAS Registry Number.
