109856-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109856-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,5 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109856-97:
(8*1)+(7*0)+(6*9)+(5*8)+(4*5)+(3*6)+(2*9)+(1*7)=165
165 % 10 = 5
So 109856-97-5 is a valid CAS Registry Number.
