159947-30-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159947-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,4 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159947-30:
(8*1)+(7*5)+(6*9)+(5*9)+(4*4)+(3*7)+(2*3)+(1*0)=185
185 % 10 = 5
So 159947-30-5 is a valid CAS Registry Number.
