Check Digit Verification of cas no
The CAS Registry Mumber 6548-30-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6548-30:
(6*6)+(5*5)+(4*4)+(3*8)+(2*3)+(1*0)=107
107 % 10 = 7
So 6548-30-7 is a valid CAS Registry Number.
