338799-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 338799-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,7,9 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 338799-40:
(8*3)+(7*3)+(6*8)+(5*7)+(4*9)+(3*9)+(2*4)+(1*0)=199
199 % 10 = 9
So 338799-40-9 is a valid CAS Registry Number.
