137432-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137432-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,3 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137432-75:
(8*1)+(7*3)+(6*7)+(5*4)+(4*3)+(3*2)+(2*7)+(1*5)=128
128 % 10 = 8
So 137432-75-8 is a valid CAS Registry Number.
