137023-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137023-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,2 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137023-07:
(8*1)+(7*3)+(6*7)+(5*0)+(4*2)+(3*3)+(2*0)+(1*7)=95
95 % 10 = 5
So 137023-07-5 is a valid CAS Registry Number.
