137018-27-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137018-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,1 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137018-27:
(8*1)+(7*3)+(6*7)+(5*0)+(4*1)+(3*8)+(2*2)+(1*7)=110
110 % 10 = 0
So 137018-27-0 is a valid CAS Registry Number.
