98243-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98243-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98243-79:
(7*9)+(6*8)+(5*2)+(4*4)+(3*3)+(2*7)+(1*9)=169
169 % 10 = 9
So 98243-79-9 is a valid CAS Registry Number.
