159016-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159016-47-4 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 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159016-47:
(8*1)+(7*5)+(6*9)+(5*0)+(4*1)+(3*6)+(2*4)+(1*7)=134
134 % 10 = 4
So 159016-47-4 is a valid CAS Registry Number.
