Check Digit Verification of cas no
The CAS Registry Mumber 199872-66-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,8,7 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 199872-66:
(8*1)+(7*9)+(6*9)+(5*8)+(4*7)+(3*2)+(2*6)+(1*6)=217
217 % 10 = 7
So 199872-66-7 is a valid CAS Registry Number.
