126839-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126839-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,3 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 126839-63:
(8*1)+(7*2)+(6*6)+(5*8)+(4*3)+(3*9)+(2*6)+(1*3)=152
152 % 10 = 2
So 126839-63-2 is a valid CAS Registry Number.
