Check Digit Verification of cas no
The CAS Registry Mumber 6416-33-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6416-33:
(6*6)+(5*4)+(4*1)+(3*6)+(2*3)+(1*3)=87
87 % 10 = 7
So 6416-33-7 is a valid CAS Registry Number.
