137005-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137005-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,0 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137005-90:
(8*1)+(7*3)+(6*7)+(5*0)+(4*0)+(3*5)+(2*9)+(1*0)=104
104 % 10 = 4
So 137005-90-4 is a valid CAS Registry Number.
