137023-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137023-12-2 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, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137023-12:
(8*1)+(7*3)+(6*7)+(5*0)+(4*2)+(3*3)+(2*1)+(1*2)=92
92 % 10 = 2
So 137023-12-2 is a valid CAS Registry Number.
