Check Digit Verification of cas no
The CAS Registry Mumber 643738-61-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,3 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 643738-61:
(8*6)+(7*4)+(6*3)+(5*7)+(4*3)+(3*8)+(2*6)+(1*1)=178
178 % 10 = 8
So 643738-61-8 is a valid CAS Registry Number.
