Check Digit Verification of cas no
The CAS Registry Mumber 10142-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,4 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10142-78:
(7*1)+(6*0)+(5*1)+(4*4)+(3*2)+(2*7)+(1*8)=56
56 % 10 = 6
So 10142-78-6 is a valid CAS Registry Number.
