Check Digit Verification of cas no
The CAS Registry Mumber 368890-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,6,8,8,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 368890-20:
(8*3)+(7*6)+(6*8)+(5*8)+(4*9)+(3*0)+(2*2)+(1*0)=194
194 % 10 = 4
So 368890-20-4 is a valid CAS Registry Number.
