168958-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168958-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,9,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 168958-90:
(8*1)+(7*6)+(6*8)+(5*9)+(4*5)+(3*8)+(2*9)+(1*0)=205
205 % 10 = 5
So 168958-90-5 is a valid CAS Registry Number.
