Check Digit Verification of cas no
The CAS Registry Mumber 217967-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,9,6 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 217967-18:
(8*2)+(7*1)+(6*7)+(5*9)+(4*6)+(3*7)+(2*1)+(1*8)=165
165 % 10 = 5
So 217967-18-5 is a valid CAS Registry Number.
