269730-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 269730-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,7,3 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 269730-99:
(8*2)+(7*6)+(6*9)+(5*7)+(4*3)+(3*0)+(2*9)+(1*9)=186
186 % 10 = 6
So 269730-99-6 is a valid CAS Registry Number.
