1268519-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1268519-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,5,1 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1268519-40:
(9*1)+(8*2)+(7*6)+(6*8)+(5*5)+(4*1)+(3*9)+(2*4)+(1*0)=179
179 % 10 = 9
So 1268519-40-9 is a valid CAS Registry Number.
