Check Digit Verification of cas no
The CAS Registry Mumber 257947-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,9,4 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 257947-33:
(8*2)+(7*5)+(6*7)+(5*9)+(4*4)+(3*7)+(2*3)+(1*3)=184
184 % 10 = 4
So 257947-33-4 is a valid CAS Registry Number.
