Check Digit Verification of cas no
The CAS Registry Mumber 603983-67-1 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 603983-67:
(8*6)+(7*0)+(6*3)+(5*9)+(4*8)+(3*3)+(2*6)+(1*7)=171
171 % 10 = 1
So 603983-67-1 is a valid CAS Registry Number.
