Check Digit Verification of cas no
The CAS Registry Mumber 142073-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142073-33:
(8*1)+(7*4)+(6*2)+(5*0)+(4*7)+(3*3)+(2*3)+(1*3)=94
94 % 10 = 4
So 142073-33-4 is a valid CAS Registry Number.
