1258302-96-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258302-96-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,3,0 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1258302-96:
(9*1)+(8*2)+(7*5)+(6*8)+(5*3)+(4*0)+(3*2)+(2*9)+(1*6)=153
153 % 10 = 3
So 1258302-96-3 is a valid CAS Registry Number.
