Check Digit Verification of cas no
The CAS Registry Mumber 109296-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,9 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109296-49:
(8*1)+(7*0)+(6*9)+(5*2)+(4*9)+(3*6)+(2*4)+(1*9)=143
143 % 10 = 3
So 109296-49-3 is a valid CAS Registry Number.
