373357-14-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 373357-14-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,3,3,5 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 373357-14:
(8*3)+(7*7)+(6*3)+(5*3)+(4*5)+(3*7)+(2*1)+(1*4)=153
153 % 10 = 3
So 373357-14-3 is a valid CAS Registry Number.
