1295567-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1295567-91-7 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 1295567-91:
(9*1)+(8*2)+(7*9)+(6*5)+(5*5)+(4*6)+(3*7)+(2*9)+(1*1)=207
207 % 10 = 7
So 1295567-91-7 is a valid CAS Registry Number.
