Check Digit Verification of cas no
The CAS Registry Mumber 137303-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137303-19:
(8*1)+(7*3)+(6*7)+(5*3)+(4*0)+(3*3)+(2*1)+(1*9)=106
106 % 10 = 6
So 137303-19-6 is a valid CAS Registry Number.
