62238-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62238-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,2,3 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 62238-37:
(7*6)+(6*2)+(5*2)+(4*3)+(3*8)+(2*3)+(1*7)=113
113 % 10 = 3
So 62238-37-3 is a valid CAS Registry Number.
