137726-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137726-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,2 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137726-18:
(8*1)+(7*3)+(6*7)+(5*7)+(4*2)+(3*6)+(2*1)+(1*8)=142
142 % 10 = 2
So 137726-18-2 is a valid CAS Registry Number.
