Check Digit Verification of cas no
The CAS Registry Mumber 134978-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,7 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134978-52:
(8*1)+(7*3)+(6*4)+(5*9)+(4*7)+(3*8)+(2*5)+(1*2)=162
162 % 10 = 2
So 134978-52-2 is a valid CAS Registry Number.
