723296-98-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 723296-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,3,2,9 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 723296-98:
(8*7)+(7*2)+(6*3)+(5*2)+(4*9)+(3*6)+(2*9)+(1*8)=178
178 % 10 = 8
So 723296-98-8 is a valid CAS Registry Number.
