128015-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128015-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,1 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128015-21:
(8*1)+(7*2)+(6*8)+(5*0)+(4*1)+(3*5)+(2*2)+(1*1)=94
94 % 10 = 4
So 128015-21-4 is a valid CAS Registry Number.
