909797-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909797-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,7,9 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 909797-77:
(8*9)+(7*0)+(6*9)+(5*7)+(4*9)+(3*7)+(2*7)+(1*7)=239
239 % 10 = 9
So 909797-77-9 is a valid CAS Registry Number.
