128763-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128763-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,6 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128763-70:
(8*1)+(7*2)+(6*8)+(5*7)+(4*6)+(3*3)+(2*7)+(1*0)=152
152 % 10 = 2
So 128763-70-2 is a valid CAS Registry Number.
