159831-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159831-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,3 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 159831-45:
(8*1)+(7*5)+(6*9)+(5*8)+(4*3)+(3*1)+(2*4)+(1*5)=165
165 % 10 = 5
So 159831-45-5 is a valid CAS Registry Number.
