Check Digit Verification of cas no
The CAS Registry Mumber 105962-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,6 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105962-55:
(8*1)+(7*0)+(6*5)+(5*9)+(4*6)+(3*2)+(2*5)+(1*5)=128
128 % 10 = 8
So 105962-55-8 is a valid CAS Registry Number.
