Check Digit Verification of cas no
The CAS Registry Mumber 1783-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1783-81:
(6*1)+(5*7)+(4*8)+(3*3)+(2*8)+(1*1)=99
99 % 10 = 9
So 1783-81-9 is a valid CAS Registry Number.
