750839-86-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 750839-86-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,0,8,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 750839-86:
(8*7)+(7*5)+(6*0)+(5*8)+(4*3)+(3*9)+(2*8)+(1*6)=192
192 % 10 = 2
So 750839-86-2 is a valid CAS Registry Number.
