115961-48-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115961-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,6 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115961-48:
(8*1)+(7*1)+(6*5)+(5*9)+(4*6)+(3*1)+(2*4)+(1*8)=133
133 % 10 = 3
So 115961-48-3 is a valid CAS Registry Number.
