159014-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159014-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,0,1 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 159014-85:
(8*1)+(7*5)+(6*9)+(5*0)+(4*1)+(3*4)+(2*8)+(1*5)=134
134 % 10 = 4
So 159014-85-4 is a valid CAS Registry Number.
