137844-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137844-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,4 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 137844-99:
(8*1)+(7*3)+(6*7)+(5*8)+(4*4)+(3*4)+(2*9)+(1*9)=166
166 % 10 = 6
So 137844-99-6 is a valid CAS Registry Number.
