1269617-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1269617-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,6,1 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1269617-53:
(9*1)+(8*2)+(7*6)+(6*9)+(5*6)+(4*1)+(3*7)+(2*5)+(1*3)=189
189 % 10 = 9
So 1269617-53-9 is a valid CAS Registry Number.
