Check Digit Verification of cas no
The CAS Registry Mumber 66869-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,6 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66869-42:
(7*6)+(6*6)+(5*8)+(4*6)+(3*9)+(2*4)+(1*2)=179
179 % 10 = 9
So 66869-42-9 is a valid CAS Registry Number.
