The CAS Registry Mumber 20197-92-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,9 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.Calculate Digit Verification of CAS Registry Number 20197-92:
(7*2)+(6*0)+(5*1)+(4*9)+(3*7)+(2*9)+(1*2)=96
96 % 10 = 6
So 20197-92-6 is a valid CAS Registry Number.
