Check Digit Verification of cas no
The CAS Registry Mumber 106105-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,1,0 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106105-29:
(8*1)+(7*0)+(6*6)+(5*1)+(4*0)+(3*5)+(2*2)+(1*9)=77
77 % 10 = 7
So 106105-29-7 is a valid CAS Registry Number.
