159554-00-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159554-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,5,5 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159554-00:
(8*1)+(7*5)+(6*9)+(5*5)+(4*5)+(3*4)+(2*0)+(1*0)=154
154 % 10 = 4
So 159554-00-4 is a valid CAS Registry Number.
