Check Digit Verification of cas no
The CAS Registry Mumber 105299-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,9 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105299-33:
(8*1)+(7*0)+(6*5)+(5*2)+(4*9)+(3*9)+(2*3)+(1*3)=120
120 % 10 = 0
So 105299-33-0 is a valid CAS Registry Number.
