108999-14-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108999-14-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,9,9 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 108999-14:
(8*1)+(7*0)+(6*8)+(5*9)+(4*9)+(3*9)+(2*1)+(1*4)=170
170 % 10 = 0
So 108999-14-0 is a valid CAS Registry Number.
