Check Digit Verification of cas no

The CAS Registry Mumber 199792-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,9 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 199792-34:
(8*1)+(7*9)+(6*9)+(5*7)+(4*9)+(3*2)+(2*3)+(1*4)=212
212 % 10 = 2
So 199792-34-2 is a valid CAS Registry Number.
