Check Digit Verification of cas no
The CAS Registry Mumber 1308-14-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1308-14:
(6*1)+(5*3)+(4*0)+(3*8)+(2*1)+(1*4)=51
51 % 10 = 1
So 1308-14-1 is a valid CAS Registry Number.
