15021-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15021-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,2 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15021-43:
(7*1)+(6*5)+(5*0)+(4*2)+(3*1)+(2*4)+(1*3)=59
59 % 10 = 9
So 15021-43-9 is a valid CAS Registry Number.
