Check Digit Verification of cas no
The CAS Registry Mumber 356783-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,6,7,8 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 356783-26:
(8*3)+(7*5)+(6*6)+(5*7)+(4*8)+(3*3)+(2*2)+(1*6)=181
181 % 10 = 1
So 356783-26-1 is a valid CAS Registry Number.
