Check Digit Verification of cas no
The CAS Registry Mumber 137890-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,9 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137890-04:
(8*1)+(7*3)+(6*7)+(5*8)+(4*9)+(3*0)+(2*0)+(1*4)=151
151 % 10 = 1
So 137890-04-1 is a valid CAS Registry Number.
