137577-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137577-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,7 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137577-08:
(8*1)+(7*3)+(6*7)+(5*5)+(4*7)+(3*7)+(2*0)+(1*8)=153
153 % 10 = 3
So 137577-08-3 is a valid CAS Registry Number.
