238743-47-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 238743-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,7,4 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 238743-47:
(8*2)+(7*3)+(6*8)+(5*7)+(4*4)+(3*3)+(2*4)+(1*7)=160
160 % 10 = 0
So 238743-47-0 is a valid CAS Registry Number.
