137299-09-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137299-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,9 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137299-09:
(8*1)+(7*3)+(6*7)+(5*2)+(4*9)+(3*9)+(2*0)+(1*9)=153
153 % 10 = 3
So 137299-09-3 is a valid CAS Registry Number.
