400783-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 400783-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,8 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 400783-41:
(8*4)+(7*0)+(6*0)+(5*7)+(4*8)+(3*3)+(2*4)+(1*1)=117
117 % 10 = 7
So 400783-41-7 is a valid CAS Registry Number.
