The CAS Registry Mumber 823809-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,3,8,0 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 823809-62:
(8*8)+(7*2)+(6*3)+(5*8)+(4*0)+(3*9)+(2*6)+(1*2)=177
177 % 10 = 7
So 823809-62-7 is a valid CAS Registry Number.
