Check Digit Verification of cas no
The CAS Registry Mumber 104311-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,1 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104311-39:
(8*1)+(7*0)+(6*4)+(5*3)+(4*1)+(3*1)+(2*3)+(1*9)=69
69 % 10 = 9
So 104311-39-9 is a valid CAS Registry Number.
