159947-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159947-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,4 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 159947-28:
(8*1)+(7*5)+(6*9)+(5*9)+(4*4)+(3*7)+(2*2)+(1*8)=191
191 % 10 = 1
So 159947-28-1 is a valid CAS Registry Number.
