Check Digit Verification of cas no
The CAS Registry Mumber 70591-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,9 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 70591-46:
(7*7)+(6*0)+(5*5)+(4*9)+(3*1)+(2*4)+(1*6)=127
127 % 10 = 7
