The CAS Registry Mumber 29936-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,3 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29936-92:
(7*2)+(6*9)+(5*9)+(4*3)+(3*6)+(2*9)+(1*2)=163
163 % 10 = 3
So 29936-92-3 is a valid CAS Registry Number.
