2383-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2383-98-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,8 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.Calculate Digit Verification of CAS Registry Number 2383-98:
(6*2)+(5*3)+(4*8)+(3*3)+(2*9)+(1*8)=94
94 % 10 = 4
So 2383-98-4 is a valid CAS Registry Number.
