373385-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 373385-51-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,3,3,8 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 373385-51:
(8*3)+(7*7)+(6*3)+(5*3)+(4*8)+(3*5)+(2*5)+(1*1)=164
164 % 10 = 4
So 373385-51-4 is a valid CAS Registry Number.
