123475-38-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123475-38-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,7 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123475-38:
(8*1)+(7*2)+(6*3)+(5*4)+(4*7)+(3*5)+(2*3)+(1*8)=117
117 % 10 = 7
So 123475-38-7 is a valid CAS Registry Number.
