299926-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 299926-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,9,2 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 299926-55:
(8*2)+(7*9)+(6*9)+(5*9)+(4*2)+(3*6)+(2*5)+(1*5)=219
219 % 10 = 9
So 299926-55-9 is a valid CAS Registry Number.
