Check Digit Verification of cas no
The CAS Registry Mumber 214544-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,5,4 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 214544-12:
(8*2)+(7*1)+(6*4)+(5*5)+(4*4)+(3*4)+(2*1)+(1*2)=104
104 % 10 = 4
So 214544-12-4 is a valid CAS Registry Number.
