Check Digit Verification of cas no
The CAS Registry Mumber 105376-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,3,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 105376-26:
(8*1)+(7*0)+(6*5)+(5*3)+(4*7)+(3*6)+(2*2)+(1*6)=109
109 % 10 = 9
So 105376-26-9 is a valid CAS Registry Number.
