82393-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82393-83-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,9 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82393-83:
(7*8)+(6*2)+(5*3)+(4*9)+(3*3)+(2*8)+(1*3)=147
147 % 10 = 7
So 82393-83-7 is a valid CAS Registry Number.
