Check Digit Verification of cas no
The CAS Registry Mumber 1677681-05-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,7,7,6,8 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1677681-05:
(9*1)+(8*6)+(7*7)+(6*7)+(5*6)+(4*8)+(3*1)+(2*0)+(1*5)=218
218 % 10 = 8
So 1677681-05-8 is a valid CAS Registry Number.
