99842-49-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99842-49-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,4 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 99842-49:
(7*9)+(6*9)+(5*8)+(4*4)+(3*2)+(2*4)+(1*9)=196
196 % 10 = 6
So 99842-49-6 is a valid CAS Registry Number.
