Check Digit Verification of cas no
The CAS Registry Mumber 1719-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,1 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1719-83:
(6*1)+(5*7)+(4*1)+(3*9)+(2*8)+(1*3)=91
91 % 10 = 1
So 1719-83-1 is a valid CAS Registry Number.
