83948-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83948-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,4 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83948-20:
(7*8)+(6*3)+(5*9)+(4*4)+(3*8)+(2*2)+(1*0)=163
163 % 10 = 3
So 83948-20-3 is a valid CAS Registry Number.
