Check Digit Verification of cas no
The CAS Registry Mumber 1669-47-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1669-47:
(6*1)+(5*6)+(4*6)+(3*9)+(2*4)+(1*7)=102
102 % 10 = 2
So 1669-47-2 is a valid CAS Registry Number.
