Check Digit Verification of cas no
The CAS Registry Mumber 109671-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,7 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109671-49:
(8*1)+(7*0)+(6*9)+(5*6)+(4*7)+(3*1)+(2*4)+(1*9)=140
140 % 10 = 0
So 109671-49-0 is a valid CAS Registry Number.
