Check Digit Verification of cas no
The CAS Registry Mumber 137819-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137819-03:
(8*1)+(7*3)+(6*7)+(5*8)+(4*1)+(3*9)+(2*0)+(1*3)=145
145 % 10 = 5
So 137819-03-5 is a valid CAS Registry Number.
