299178-59-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 299178-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,1,7 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 299178-59:
(8*2)+(7*9)+(6*9)+(5*1)+(4*7)+(3*8)+(2*5)+(1*9)=209
209 % 10 = 9
So 299178-59-9 is a valid CAS Registry Number.
