123783-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123783-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123783-66:
(8*1)+(7*2)+(6*3)+(5*7)+(4*8)+(3*3)+(2*6)+(1*6)=134
134 % 10 = 4
So 123783-66-4 is a valid CAS Registry Number.
