137254-69-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137254-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,5 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137254-69:
(8*1)+(7*3)+(6*7)+(5*2)+(4*5)+(3*4)+(2*6)+(1*9)=134
134 % 10 = 4
So 137254-69-4 is a valid CAS Registry Number.
