Check Digit Verification of cas no
The CAS Registry Mumber 603983-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,3,9,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 603983-66:
(8*6)+(7*0)+(6*3)+(5*9)+(4*8)+(3*3)+(2*6)+(1*6)=170
170 % 10 = 0
So 603983-66-0 is a valid CAS Registry Number.
