128961-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128961-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,6 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128961-15:
(8*1)+(7*2)+(6*8)+(5*9)+(4*6)+(3*1)+(2*1)+(1*5)=149
149 % 10 = 9
So 128961-15-9 is a valid CAS Registry Number.
