Check Digit Verification of cas no
The CAS Registry Mumber 3219-73-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3219-73:
(6*3)+(5*2)+(4*1)+(3*9)+(2*7)+(1*3)=76
76 % 10 = 6
So 3219-73-6 is a valid CAS Registry Number.
