Check Digit Verification of cas no
The CAS Registry Mumber 68048-39-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,4 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68048-39:
(7*6)+(6*8)+(5*0)+(4*4)+(3*8)+(2*3)+(1*9)=145
145 % 10 = 5
So 68048-39-5 is a valid CAS Registry Number.
