Check Digit Verification of cas no
The CAS Registry Mumber 19081-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,8 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19081-37:
(7*1)+(6*9)+(5*0)+(4*8)+(3*1)+(2*3)+(1*7)=109
109 % 10 = 9
So 19081-37-9 is a valid CAS Registry Number.
