The CAS Registry Mumber 138902-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,0 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138902-12:
(8*1)+(7*3)+(6*8)+(5*9)+(4*0)+(3*2)+(2*1)+(1*2)=132
132 % 10 = 2
So 138902-12-2 is a valid CAS Registry Number.
