137588-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137588-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,8 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137588-60:
(8*1)+(7*3)+(6*7)+(5*5)+(4*8)+(3*8)+(2*6)+(1*0)=164
164 % 10 = 4
So 137588-60-4 is a valid CAS Registry Number.
