159898-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159898-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,9 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159898-40:
(8*1)+(7*5)+(6*9)+(5*8)+(4*9)+(3*8)+(2*4)+(1*0)=205
205 % 10 = 5
So 159898-40-5 is a valid CAS Registry Number.
