159891-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159891-29-9 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 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 159891-29:
(8*1)+(7*5)+(6*9)+(5*8)+(4*9)+(3*1)+(2*2)+(1*9)=189
189 % 10 = 9
So 159891-29-9 is a valid CAS Registry Number.
