99683-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99683-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,8 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99683-07:
(7*9)+(6*9)+(5*6)+(4*8)+(3*3)+(2*0)+(1*7)=195
195 % 10 = 5
So 99683-07-5 is a valid CAS Registry Number.
