299938-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 299938-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,9,3 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 299938-97:
(8*2)+(7*9)+(6*9)+(5*9)+(4*3)+(3*8)+(2*9)+(1*7)=239
239 % 10 = 9
So 299938-97-9 is a valid CAS Registry Number.
