1295567-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1295567-93-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,5,5,6 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1295567-93:
(9*1)+(8*2)+(7*9)+(6*5)+(5*5)+(4*6)+(3*7)+(2*9)+(1*3)=209
209 % 10 = 9
So 1295567-93-9 is a valid CAS Registry Number.
