434956-07-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 434956-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,4,9,5 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 434956-07:
(8*4)+(7*3)+(6*4)+(5*9)+(4*5)+(3*6)+(2*0)+(1*7)=167
167 % 10 = 7
So 434956-07-7 is a valid CAS Registry Number.
