672310-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 672310-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,3,1 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 672310-33:
(8*6)+(7*7)+(6*2)+(5*3)+(4*1)+(3*0)+(2*3)+(1*3)=137
137 % 10 = 7
So 672310-33-7 is a valid CAS Registry Number.
