137741-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137741-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,4 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137741-09:
(8*1)+(7*3)+(6*7)+(5*7)+(4*4)+(3*1)+(2*0)+(1*9)=134
134 % 10 = 4
So 137741-09-4 is a valid CAS Registry Number.
