Check Digit Verification of cas no
The CAS Registry Mumber 134645-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,4 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134645-11:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*5)+(2*1)+(1*1)=117
117 % 10 = 7
So 134645-11-7 is a valid CAS Registry Number.
