Check Digit Verification of cas no
The CAS Registry Mumber 18704-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,0 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18704-67:
(7*1)+(6*8)+(5*7)+(4*0)+(3*4)+(2*6)+(1*7)=121
121 % 10 = 1
So 18704-67-1 is a valid CAS Registry Number.
