127983-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127983-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,8 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127983-33:
(8*1)+(7*2)+(6*7)+(5*9)+(4*8)+(3*3)+(2*3)+(1*3)=159
159 % 10 = 9
So 127983-33-9 is a valid CAS Registry Number.
