83548-79-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83548-79-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,4 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83548-79:
(7*8)+(6*3)+(5*5)+(4*4)+(3*8)+(2*7)+(1*9)=162
162 % 10 = 2
So 83548-79-2 is a valid CAS Registry Number.
