Check Digit Verification of cas no
The CAS Registry Mumber 3071-73-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,7 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3071-73:
(6*3)+(5*0)+(4*7)+(3*1)+(2*7)+(1*3)=66
66 % 10 = 6
So 3071-73-6 is a valid CAS Registry Number.
